How to get selection menu for operator.

I have seen in many streams of people opening up GSX request a service and a menu with all the airlines comes up for them to choose from. When I select a service no operator selection menu appears.

Under “Customize Airport Positions” there’s a field “Airline codes”. You can use this to manually insert multiples codes thatGSX will use as choices for ground handlers. Else GSX will use it’s -default- selection. See page 33 of the manual.

I already know about that. I am talking about the menu that appears that let’s you quickly select the ground services conpany that I do not have.

The operator selection menu will only come if at a specific airport there are more than one candidate operators, if there's only one, it would be silly to present a menu with only one choice, so the menu is skipped.
