I understand what you're looking for and I believe that is being worked on. In the meantime...   You can currently select any existing profile for the Alpha or Bravo even after the sim has been started. If you have an aircraft loaded, you'd simply have to reload the aircraft after selecting the appropriate configuration profile for the aircraft you plan to fly.   Another solution would be to use FSUIPC, which allows you to create separate aircraft profiles for all controllers.   Best wishes.  

GSmini is modelled on both smaller busses and A330. As for the original issue reported. I have not been able to recreate this myself but will keep an eye out for it.
