Remove UPS and Fedex equipment choices?

[DMdoc]

Among the choices for equipment to handle my aircraft, there is (always/frequently) UPS and Fedex, as well as choices like Delta or Southwest.
Question 1: Do either UPS or Fedex ever handle real-life passenger airliners?
Question 2: Is there any way I can remove those two choices from the listing of available handlers?
Thanks in advance -- I love GSX and GSX2!

The cargo operators are suggested when the parking is listed a cargo in the scenery AFCAD.

Of course, GSX cannot possibly know if the parking is flagged as cargo because it IS a cargo parking, or it's just an error/oversight of the scenery developers. That's why you have the option to override the parking type in the GSX customization window.
