It's not possible to have jetways programmed to dock with a click, since the main reason of using GSX L2 and SODE, is allowing more than one jetway and, if more than one jetway works on more than one door, the program MUST ask you which jetway you would want to dock to which door.
You can obtain something similar, by enabling the automatic services option in GSX, which will perform all services automatically and, in case of jetways, it will dock them automatically. However, if something like my first example happens, it MIGHT be possible that some double jetways might cross with each other, since the program cannnot possibly know if two jetways that can work with two doors might eventually cross with each other, so in that case, it would be best not to use the automatic servicing.
Of course, GSX is available in Trial version, so you can see for yourself how it works.
