When you assign keybindings in FSUIPC7 you get the option to make the binding aircraft specific or all aircraft. So to set up a specific aircraft I go through the search function to see what event is operating when I throw a switch in the VC. I then assign this to a switch on my home cockpit and tick “Aircraft specific” in FSUIPC7 on the assignments page. Hope this answers your question. No, I am not familiar with AA0s.
