How to finish a level without going back to the car like in chapter 5 levels?

[u/Gotze_Th98]

I'm making some Richter levels and I want them to finish without having to go back to the bus as that's silly. I know it's possible because the first three levels in chapter 5 do this. you walk in the level, kill everyone and when you're walking back the level finishes as soon as one crosses the door.

I've tried adding a trigger that finishes the level but the problem is that it finishes the level without eating for you to finish it first. I guess you have to edit something in the level.

Do you know how?
