Hi,
I'm Amro, a fellow Microsoft user and I’m happy to look into this for you.
Unfortunate, it's not possible to use Teams app on iPad as a designated controller for your campus wide system.

I advise you also to check > Manage collaboration experiences in Teams for iOS and Android with Microsoft Intune: https://learn.microsoft.com/en-us/mem/intune/ap... Where you can see that Teams for iOS and Android only supports app settings that allow unified endpoint management, like Microsoft Endpoint Manager, administrators to customize the behavior of the app.
I hope this helps, please feel free to reply to this if you need any further Assistance.
Kindly
Amro
