New Feature Turn off all players

Hi
I am running a multi room system which uses 6 raspberry pi’s + hifiberry and 3 raspberry pi’s as independant touchscreen controllers. I would like a feature on jivelite(if possible ) but as an App if not. Which turns off all the players in one go. This would be useful for when we go out and saves having to go around each room and turn off individually.

Max2Play is brilliant one of the best systems I’ve used!
