Use Compositions as 3D Model's Texture

Previously requested but wanted to add a few addendums to this really desired item:
Love the increasing native 3D capabilities of After Effects and I really wish the workflow of nesting compositions to build complex animations was reflected in the new Advanced 3D renderer. I would love to be able to select or reference a composition from the project panel to be used as a 3D layer's texture.

As an animator / designer for screens for live events, we often use After Effects not only to build out large pieces of content (multiple synchronous 4K+ feeds) but also to previsualize in real-time what our content will look like. This is super helpful because we don't have to round-trip still frames or large renders between AE and another DCC. However, creating these previsualization setups can take a large amount of time, much of which having compositions UV-mapped onto 3D objects would save an immense amount of time. For instance, for a curved screen we often are cutting up a composition into multiple slices and rotating them individually in 3D.
