"Perform additional heavy (C/D) checks even if not expired" not doing D checks

When removing a plane from storage, the check box to "perform C/D checks even if not expired" is only doing C checks, not D checks, even when the C check is already expired and the D check is less than 6 months away.

Game World: Airline Generations

Airline: Air Riga

Suggestion: provide separate check boxes for doing a manual C or D check when removing from storage, so the game doesn't have to try to guess which one you want to do from a single check box. Similar to the manual A/B check selections when scheduling planes.
