Multi Devices 3 iPads

Hi, so i got my three iPads connected and all working with ableton. is there a way i can extended the mixer board across all iPads rather mirroring of each other? when i’m staring at one iPad on settings>multi i dont see other the devices connected to each other, but when staring at all three iPads on same settings i see each of them having only 1 device connected but with its own iPad names. im a bit confused how this could work. i remeber on the old touchable your able to extended the mixer board across iPads and when you swipe from the mixer on one iPad it also moves the others as if they were as one. let me know anyone thanks.
