Can we please fix the aircraft convoy nonsense?

In some situations you move an aircraft from one airfield to another and instead of staying as a plane it transforms itself into a truck. Well great if you want to move it overland but why oh why cant the gamers fix this rubbish!!

PLEASE fix it. It is so damn irrritating. A solution is simple just put in a pop up question viz Do you want this aircraft to become a convoy y/n. Simples.
