TV Sync shortcut

Dear,

Thank you for your app. I use on my cinema room the sync fonction and that amazing.

How can I activate/desactivate the function sync ?

Per exemple I remap whit buttom mapper on my remote or when I push buttom on my philips hue buttom ?

I have read many topic about shortcut but I have find nothing to do shortcut on my nvidia shield. Many topic speak about smartphone app but I want sync whit picture on my cinema room.

Thank you

Best regard
