What is the best way to provide an AutoMappingOverride for an interface in Fluentnhibernate automapper

In my search for a database filter for the entire version of the application, I wrote the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using FluentNHibernate.Automapping;
using FluentNHibernate.Automapping.Alterations;
using FluentNHibernate.Mapping;
using MvcExtensions.Model;
using NHibernate;

namespace MvcExtensions.Services.Impl.FluentNHibernate
{
    public interface IVersionAware
    {
        string Version { get; set; }
    }

    public class VersionFilter : FilterDefinition
    {
        const string FILTERNAME = "MyVersionFilter";
        const string COLUMNNAME = "Version";

        public VersionFilter()
        {
            this.WithName(FILTERNAME)
                .WithCondition("Version = :"+COLUMNNAME)
                .AddParameter(COLUMNNAME, NHibernateUtil.String );
        }

        public static void EnableVersionFilter(ISession session,string version)
        {
            session.EnableFilter(FILTERNAME).SetParameter(COLUMNNAME, version);
        }

        public static void DisableVersionFilter(ISession session)
        {
            session.DisableFilter(FILTERNAME);
        }
    }

    public class VersionAwareOverride : IAutoMappingOverride<IVersionAware>
    {
        #region IAutoMappingOverride<IVersionAware> Members

        public void Override(AutoMapping<IVersionAware> mapping)
        {
            mapping.ApplyFilter<VersionFilter>();
        }
        #endregion
    }

}

But, since overrides do not work on interfaces, I am looking for a way to implement this. I am currently using this (rather cumbersome) method for each class that implements the interface:

public class SomeVersionedEntity : IModelId, IVersionAware
{
    public virtual int Id { get; set; }
    public virtual string Version { get; set; }
}

public class SomeVersionedEntityOverride : IAutoMappingOverride<SomeVersionedEntity>
{
    #region IAutoMappingOverride<SomeVersionedEntity> Members

    public void Override(AutoMapping<SomeVersionedEntity> mapping)
    {
        mapping.ApplyFilter<VersionFilter>();
    }

    #endregion
}

I look at the interfaces of IClassmap, etc., but they do not seem to provide a way to access the ApplyFilter method, so I did not understand here ...

Since I am probably not the first to have this problem, I am pretty sure that this should be possible; I'm just not quite sure how this works.

EDIT: I came a little closer to a universal solution:

Here's how I tried to solve it:

, :

public abstract class AutomappingInterfaceAlteration<I> : IAutoMappingAlteration
{
    public void Alter(AutoPersistenceModel model)
    {
        model.OverrideAll(map =>
        {
            var recordType = map.GetType().GetGenericArguments().Single();
            if (typeof(I).IsAssignableFrom(recordType))
            {
                this.GetType().GetMethod("overrideStuff").MakeGenericMethod(recordType).Invoke(this, new object[] { model });
            }
        });
    }

    public void overrideStuff<T>(AutoPersistenceModel pm) where T : I
    {
        pm.Override<T>( a => Override(a));
    }

    public abstract void Override<T>(AutoMapping<T> am) where T:I;
}

:

public class VersionAwareAlteration : AutomappingInterfaceAlteration<IVersionAware>
{
    public override void Override<T>(AutoMapping<T> am)
    {
        am.Map(x => x.Version).Column("VersionTest");
        am.ApplyFilter<VersionFilter>();
    }
}

2: : "Override" , :

public abstract class PersistenceOverride<I> 
{

    public void DoOverrides(AutoPersistenceModel model,IEnumerable<Type> Mytypes)
    {
        foreach(var t in Mytypes.Where(x=>typeof(I).IsAssignableFrom(x)))
            ManualOverride(t,model);
    }

    private void ManualOverride(Type recordType,AutoPersistenceModel model)
    {
        var t_amt = typeof(AutoMapping<>).MakeGenericType(recordType);
        var t_act = typeof(Action<>).MakeGenericType(t_amt);
        var m = typeof(PersistenceOverride<I>)
                .GetMethod("MyOverride")
                .MakeGenericMethod(recordType)
                .Invoke(this, null);
        model.GetType().GetMethod("Override").MakeGenericMethod(recordType).Invoke(model, new object[] { m });
    }

    public abstract Action<AutoMapping<T>> MyOverride<T>() where T:I;
}

public class VersionAwareOverride : PersistenceOverride<IVersionAware>
{
    public override Action<AutoMapping<T>> MyOverride<T>()
    {
        return am =>
        {
            am.Map(x => x.Version).Column(VersionFilter.COLUMNNAME);
            am.ApplyFilter<VersionFilter>();
        };
    }
}

hbm "".... , - ?
