Doing some comp animation for a news style panel PIP setup where I want to bring a given PIP full screen on top of all others. Using the Key layers This has been pretty easy along with z priority option so I can make key 1 above all others when full screen. I haven't figured out a way to do this when using the ME layers. I can animate one to full screen but layer D for example is below all others. I thought about trying to setup macros to basically move who ever needs to be on full screen to the top layer while also moving it to the right spot but that seems overly complicated and prone to issues.

At the moment I just use the key layers and it works great but there are some events coming up where I will need 5 or 6 people on screen and only have the 4 keys.
