Mirror iPad screen to multiple screens

Hello, 

I have tested successfully the new iOS QuickSupport App and it works perfectly.

As I work as a teacher and as all my students have iPads, I have a special request: 

I would like to be able to mirror my iPad Pro screen to the screens of all my student iPads (approx. 30) so that they can follow what I'm presenting or writing (in Notability for example). 

At the moment the limitiation is set to one device that can watch my screen, is it possible to change this limit? 

thanks in advance

Ben
