Not related to a problem.

Describe the solution you'd like
Being able to trigger a tracker if a player goes through a door or a specific "zone" (similar to how TP works).
For example swapping vision to "dark vision" in a specific location, whenever they go through a door or entering a given room - with a dedicated "zone" created as an invisible token.
