Implement FBX Merge as Folder [SUGGESTION]

I build my levels in Blender, and want them in the same object, but not the same mesh. I would like if imports would work like Unity’s import system.
An option on the FBX importer: “Combine objects” (radio button with “combine meshes”), would make it so when the model is dragged into the scene, you could select each individual object, as saved by Blender.

The picture is of Unity. The blue top parent is the name of the model, and everything else are children.

This would make editing much simpler for me. Thanks!
