could be reaching but since it says room not found I assume all the elevators on the map have been pre-loaded and uses data from a table.

I thought I might be able to build my own, I copy some tiles from a police station elevator (without activating the button) using tile picker I can change floors with fly mode, so went to a random spot and copied everything and made up a small room at -1 just below, made sure everything was aligned

...I hoped it would generate a working elevator but either its not possible or i'm doing it wrong.

It says room not found in log, so if not is there a way I can mod the file to include x,y, or maybe an option to set custom cords, any help appreciated.
