Add new field to existing provider package object with yml configuration

Question

I am trying to add a many-to-one association to an existing entity in a vendor bundle.

This is my essence in a vendor bundle: -

class Post
{
    private $id;

    private $title;

    private $accroche;

    private $article;

    private $categories;

    private $comments;

    private $created;

    private $updated;

    private $publied;
}

And this is the orm mapping file for the Post object in the provider package: -

Mv\BlogBundle\Entity\AdminBlog\Post:
  type:                 entity
  table:                null
  repositoryClass:      Mv\BlogBundle\Entity\AdminBlog\PostRepository
  id:
    id:
      type:             integer
      generator:
        strategy:       AUTO

  fields:
    title:
      type:             string
      length:           150
    accroche:
      type:             text
    article:
      type:             text
    created:
      type:             datetime
      gedmo:
        timestampable:
          on: create
    updated:
      type:             datetime
      gedmo:
        timestampable:
          on: update
    publied:
      type:             datetime

  manyToMany:
    categories:
      targetEntity:   Mv\BlogBundle\Entity\AdminBlog\Category
      inversedBy:     posts
      joinTable:
        name:         post_category
        joinColumns:
          post_id:
            referencedColumnName: id
            onDelete:             CASCADE
        inverseJoinColumns:
          category_id:
            referencedColumnName: id
            onDelete:             RESTRICT

  oneToMany:
    comments:
      targetEntity:   Mv\BlogBundle\Entity\AdminBlog\Comment
      mappedBy:       post

I created a child package of my vendor package. I explored mappedSuperclass and tried other inheritance methods. But none of them worked, just adding an association to the Publish object.

I just want to have something like the following (tried adding it to the orm mapping file, but didn't work): -

manyToOne:
  user:
    targetEntity:   TP\Bundle\MainBundle\Entity\User
    joinColumns:
        user_id:
          referencedColumnName: id
