Saving "dark-cockpit" planes and reloading active syste

Hi,a thing that make me frustrated is that since I have no much time to fly, I often cannot complete a flight in a session, so I have to save the flight. Unfortunately, with planes like the splendid Frolov's Dash 8-300, all the plane systems are shut down when you reload them. Is there a way to save these planes/panels variables in order to get the systems working as they were when you saved the flight? Thank youFrancesco
