Custom Collision Object Type?

Is it possible to make a new Collision Object Type that is not World Dynamic, World Static, Pawn etc?

I want to make make a unique object, or series of objects that have unique collision that is going to act differently than pawns, projectiles, world dynamic objects etc.

Would also be handy for organizational purposes as well.

Or: How do you manage multiple different objects and their individual properties / behaviors? The default groups seem a bit restrictive… things might get a little crowded and complicated…

Or maybe I’m missing something and this really isnt what I want to do?
