Probably the simplest thing to do this is to base it off of private notes: #TACH:H#" would put the tach in hh:mm for that aircraft, "#HOBBS:H#" would put the hobbs in hh:mm for that aircraft. Would want to do this for iOS/Android too.
Or, if that gets too complicated (since it means changing things when the aircraft selected for a flight changes), just make it a global setting (on iOS/Android as well) and go with it. Less precise, but vastly simpler to manage.
