To modify the route with the rubberband mode wasn't an option.
I intended to fly from LOAZ (Zell am See) via Hochtor Pass to LOWK (Klagenfurt)
The pass I then found blocked by clouds, so I used the route via Radstädter Tauerpass which was open.
Since I wasn't sure what would happen during flight, I left SkyDemon alone and flew the route by memory.
I will definitely try the suggested idea in simulation mode.
Thanks for that.
