Feedback Add support for multi-object editing to CinemachineVirtualCamera

Please add multi-editing support to CinemachineVirtualCamera components. Often it's the easiest workflow to place a few cameras in the scene, but then we need to adjust one or two settings to match or start as a baseline and go from there.

Also, I believe the baseline for all Unity components is support for undo, prefabs and multi-object-editing. It's probably an oversight that it's missing from Cinemachine.

Thanks for considering!
