Just for your consideration, Umberto:
Right now Walk in Gates have one Start and Exit point. So passengers arrive and depart from and to the same point in the scenery once the start point is set.
Would it be possible to set an exit point as many airports have seperate entrances and exits for arriving and departing passengers?
As example take Split. The Passengers board from the upper part of the terminal walking down the stairs. But they deboard into the lower part of the terminal.
Currently when configuring this, you have to choose one of both.
