HSM - Cancel alert by switch

Hey HE team,
I see you have a cancel alerts if switch is ON, is there anyway we can have "cancel alert by switch" and then we can have the option to use an ON or OFF switch.
I currently have a switch that im using and as long as its on all notifications can fire (push/TTS) and would really love to utilise the same switch for this cancel.
I only realised this when the mrs left for 2hrs today and if I had the switch in place I could of killed the 89 push notifications I got in that time lol

@bravenel / @mike.maxwell ?

i have my overide switch as normally off, turn it on to overide/mute.
seams to work as standaed in all the apps
