You need to create multiple version of way systems for each room if something should change in said room. If a door is open or closed or maybe something in the room has collapsed or an hole has been blown through a wall or the floor.
1. create your way systems.
2. change to required way system as needed.
Quick note: it's probably better to duplicate or copy / paste your initial way system & edit as desired.
