9-Slice 3D equivalent (27-Slice)

I would like to use something like 9-slice but in 3D to apply to meshes (that would be 27-slice or something).

There’s any solution like that?

I know this question is ancient, but I’ve just made a tutorial about one method of doing this: How to make the equivalent of a 9-slice for a 3D mesh (Unity and Blender) - YouTube
