Materials to polygon of Mesh-object

Hello, I need to assign different materials to individual polygons of a Mesh object.
Is there a Multi/Sub-Object (3DMax) equivalent in Rhinoceros or a Grasshopper plugin?

“sub-object-material” - search this forum for this term.

it is possible to assign Material per Face of a Polysurface.

I doubt it is possible for Mesh-Faces / my guess not supported for mesh-faces.
(face = “polygon”)

it s also not possible for subd-Faces:
