Objects with different Materials joined as one

Created by: enzyme69

Probably has been asked at some point, but is there a possibility or workaround in Sverchok to have a way to Join a bunch of Mesh objects, while retaining its Materials?

With Mesh Join, the Material disappear back into a single mesh.

Supposed I have a procedural Donuts made of 2 parts. My idea is to export this Donut as Alembic, where each frame will output a different shape of the donut.

Later in another Blender, I would like to load the Alembic, and hoping the material can directly connect to each Donut Part.
