How to add powershell hashtable value?

Question

I look at the list of objects Microsoft.SqlServer.Management.Smo.Serverand add them to the hash table as follows:

$instances = Get-Content -Path .\Instances.txt
$scripts = @{}

foreach ($i in $instances)
{
    $instance = New-Object Microsoft.SqlServer.Management.Smo.Server $i
    foreach($login in $instance.Logins)
    {
        $scripts.Add($instance.Name, $login.Script())       
    }
}

So far so good. Now I want to add a row to the end of the hash table value. Therefore, for the instance of $, I want to add a row to the hash table value for this instance of $. How should I do it? I started with this, but I'm not sure I'm on the right track:

foreach ($db in $instance.Databases)
{       
    foreach ($luser in $db.Users)
    {
        if(!$luser.IsSystemObject)
        {
            $scripts.Set_Item ($instance, <what do I add in here?>)
        }
    }
}

Greetings

$h= @{}

$h.add("Test", "Item")
$h; ""
$h."Test" += " is changed"
$h

Name                           Value                                                                                                                                                   
----                           -----                                                                                                                                                   
Test                           Item                                                                                                                                                    

Test                           Item is changed

I would go with this code.

$instances = Get-Content -Path .\Instances.txt
$scripts = @{}

foreach ($i in $instances)
{
    $instance = New-Object Microsoft.SqlServer.Management.Smo.Server $i
    foreach($login in $instance.Logins)
    {
        $scripts[$instance.Name] = @($scripts[$instance.Name]) + $login.Script().ToString()
    }
}

.

foreach ($db in $instance.Databases)
{
    foreach ($luser in $db.Users)
    {
        if(!$luser.IsSystemObject)
        {
            $scripts[$instance] = @($scripts[$instance]) + $luser.Script().ToString()
        }
    }
}

The result will be a hash table with each instance as a key and an array of rows, where each row is a T-SQL script for the user.

.Script() . , ,

$scripts.Set_Item ($instance, <what do I add in here?>)

$val = $scripts[$instance]
$val.Add("text to add")
$scripts.Set_Item($instance, $val)

.
