Yes, this is supported today WITHIN a single Scene.
Remember, an AIRPlayer connects to a Campaign > Screen
So lets say you make a Campaign called: MyBikeStore
and you want 5 screens in your store.
You want 2 screen divisions in each monitor to show the same content, BUT you want the 3rd screen division of each of the 5 monitors to show something else.
Simply create 5 different Screens (within a single campaign and within a single timeline), and have each monitor connect to the same COMMON campaign, but to its OWN screen.
I attached an image to better explain the setup. Hope it helps.
This is VERY POWEFULL since it allows you to share common channels between screens but still have UNIQUE channel if need be...
If you think about it, it is VERY flexible.
