Is there any way to disable/enable all or selected devices' schedules without having to go into each device individually?  This would be used to manually enable schedules when I'm away and to disable them when I return.  The only way I can see to do this is to enable geofencing and tie it to my cell phone's location but I don't want to do this given the data usage involved.  It would be nice to have a single button that would turn all or certain device schedules on or off!
