Hi Umberto,
may I make a suggestion which would improve / ease the work of profile builders.
There should be an option to 'copy' all vehicle positions (tug, stairs, marshaller, baggage trucks, etc.) from one parking position to another (or several others) - so that the position of the vehicles is the same in relation to the stop position of the aircraft as for the original position.
Is this explained understandable?
Best wishes
