Make loading Flightplan into Garmin possible in flight

I like to edit Flightplan in Navigraph charts and use it’s moving map feature. But if I want it realistic, with getting my actual SID/STAR, Appoach and destination runway incockpit/flight, I have to fiddle with my mouse to change the active Flightplan.

I wish I could just edit in Navigraph, export changes and load that into Garmin while already airborne.

Or do I miss an already exiting feature?
