Presetting aircraft prior to sim start.

Hello!
We all know of course that it's easy enough to start 'cold and dark'; but there are some functions of the aircraft that are not saved from mission to mission.
For instance; when the sim starts the magnetos in IC engines are always on and set to 'both', and the master fuel valve is equally always on.
It's a relatively minor thing; but I couldn't help wondering if its possible to set the default position of these and other functions to 'off' prior to the sim starting?
Thanx
