Collection Instance as Rigid Body with compound shapes

When creating many rigid bodies with complex shapes I often use collection instances as the base mesh with compound shapes for collision detection.

Since Instances can't be rigid bodies, an empty rigid body object has to be created that serves as an intermediary. The compound shapes and the instance are then parented to this empty object.

If a collection instance could be used as a rigid body object of the type "Compound Parent" this process would be much simpler.
