I have switched on the option that the stylus activates edit mode automatically when touching (or nearing) the screen. Then it exists edit mode automatically after 10 seconds (default 5 seconds is too short for me). Would that satisfy your use case?

It needs an ACTIVE stylus, if you read my suggestion.
Lot of people, like me, heate active stylus, because need of charge and for an occasional notation it is enough th have a normal pen vith a screen device on the back.
