Animation items changing root position (bring-forward, send-back)

Not an expert, sorry if this is a dumb idea! :)

I think it would open up a lot of fun possibilities if a group could change it's position in the root folder as part of an animation.

Ex: When an animation moves forward the group can move it's placement (up or down) to bring it in front of or behind other items. Kinda give it a 3D feel.

I know this can be imitated by making duplicate items and showing/hiding, but that's alot of work!
