This is a profile I made for my GSX Pro for KONT. I fixed most of the terminal positions for Terminal 4 and Terminal 2 using the Star Scenery KONT found on here. I also updated the pushback profiles for the gates at both terminals and made the descriptions a bit easier to understand (End Facing Left/Right). I may update the UPS parking as well at a later date but since I mostly fly airliners out of the terminals, this is the work I've done so far. Due to the placement of assets by the Star Scenery team, you may notice that at some gates, the vehicles overlap. If you do not like this, you are free to edit the vehicle positions by using the GSX editor and placing vehicles wherever else you'd like.

To add this profile, go to the AppData\Roaming\virtuali\GSX\MSFS folder and drop it in. If using the Star Scenery content, I also recommend excluding KONT from the list of airports to add the custom jetways in the GSX configurator.
