[Feature] pin group mesh type selector

[Dmeerev]

Motivation

Currently, in some way on another i need to make multiple types of mesh on one closed mesh volume object. For now I separate chunk of mesh, selecting other type, then stitching back to other half. its working, but getting consistent pairing is pain, and mostly all changes lead to self intersection errors (one half collides with other)

Proposal

If possible, make another option in dynamics group to select type of mesh object by pin group, (like face sets, but for type) instead of single whole mesh instance, maybe animatable too. in result we get single uninterrupted, unstitched mesh volume with multiple types of areas with different properties.

Thank you for the very pictorial proposal! This is somewhat related to #54.

One thing I'm not sure about is what you mean by mixing solid and shell types. A solid represents an object with volumetric deformable elements, whereas a shell represents a surface-only object. Mixing solids would imply that the interior volumetric elements gradually disappear, and I'm not sure how that should be interpreted physically.

Unless this point becomes clear, I don't think this feature can be implemented.
