"a longer answer is "sort of": it's possible to use variables in bitsy dialog to control what room a player goes to when they step through an exit; combine that with a shuffle block and you can randomize the rooms players go to - I've experimented with this as a way to create a random world layout and it's definitely possible, but I never finished the game in question partly because of how labor intensive the process was, so keep that in mind"
This much was what I needed.
Thanks Adam.
