Sonata Admin Bundle: can I add an admin child that can have different parents?

I use doctrine inheritance matching to include various objects in a comment object. This is achieved through various specific "threads" that have a one-to-many relationship with comments. Therefore, taking the History element as an example, there will be a related StoryThread object that can have many comments.

Everything works fine, but I am having problems defining the CommentAdmin class for SonataAdminBundle, which can be used as a child of the parent objects. For example, I would like to be able to use routes such as:

/admin/bundle/story/story/1/comment/list /admin/bundle/media/gallery/1/comment/list

Does anyone have directions on how I can do this? I would like to post some code snippets, but I couldn’t find the relevant documentation, so I don’t know what is the best way to start.

I tried to use SonataNewsBundle as a reference because they implemented a similar relationship between parents and child administrators between posts and comments, but it looks like it belongs to the admin (comment) (child) admin class to be hard-coded to know that it belongs to messages, and it also seems that it should have a direct many-to-one relationship with the parent object, while mine - through a separate Thread object.

Hope this makes sense! Thanks for any help.
