If I read your question right, then the answer is No.

Fs2002 only 'sees' the file named 'traffic.bgl', so all changes/additions to the AI flight plans must be done  in this file.

Hi,

Regarding AI planes at airports, you'll have to download AFCAD (and if you don't already have it, TTools) - AFCAD permits you to add/change runway & taxiway routes to airports, and you can add/modify AI parking spaces (including lining them up or changing the direction the planes park in).  To edit an "obscure" airport like Palma, you then need to go into TTools, open "CollectAirports" within it and extract all the airports available in 2002 - if Palma appears in there you can work with what's available, if not, you would have to use AFCAD to add everything mentioned above.  I realize this should be in the appropriate section but wanted to give a point in the right direction, there is much more info in the AFCAD/TTools section here, it's helped me a whole lot.
