Improve the Air Assault command

Currently, if i have a unit at province A, an airport at province B and C, and an enemy province D at range from C.

To air assault D, I can air assault to B then ferry to C, in 1 command.

But to air assault D I have to re connect when unit is at C, and issue another command.

An intelligent Air assault to D would figure that A is in Air assault range to B, ferry to C, and Air assault to D. Making Air assault more convenient without cheating.
