Reply to hardware button to record sets?

hi it's looking like more and more I will have to make my own mappings to create a button to start / stop record function for recording a mix.. was hoping there was a sneaky shortcut somewhere but does not seem to be the case..

anyone done this already..

I would prefer a 2 button combo so I don't actually press it and stop / start recording unintentionally..

something like shift + button
