G’day Alex.
I noticed (but never pursued) a menu item on the ASiair Plus which reads “Change Device” or something similar. It may be worth pursuing. Once you have set up Scope A and it is happily banging away at whatever, perhaps you can”Change Device” to the next ASiair controlling Scope B using the same tablet/phone for both.
Once the ASiair is running, and barring some malfunction, it doesn’t need access to your tablet. You could turn it off I suppose. The problem with this - assuming it is possible at all - is that if something goes wrong with ScopeA while you’re dallying with ScopeB, you won’t know about it. The list of things is endless.
Why not begin by investigating that “Change Device” setting. That may well open or close down my brilliant idea.
Alex, I came across this discussion:

It may help.
