Using Apple TV with 4 ipads- is there a way to switch units quickly when mirroring?

[bjnick]

Hi, I am a teacher and I have a new Apple TV setup (which is terrific) plus four ipads. We have mirroring set up and it's working well with an individual ipad, but what I really need is a way(or device) so that we can quickly switch ipads being mirrored. That is.....one student is showing his/her work up on the TV via mirroring. Now we want another student to show their work on a different ipad. At it stands, it is a laborious procedure to go from one to the other.....is it possible to set it up so that we can just basically go "click" and go from ipad to ipad? I would imagine this is something that people are increasingly going to demand.....

Thanks for any wisdom.
