So the "Room from" and "Room to" would be a bit more useful if there was a way to control the parameters. Perhaps if doors had an additional symbol that drove those and could be toggled (like the door flip). If not that maybe a relational parameter between adjacent room?
It would really be nice to control those parameters other than by the original inserted swing direction.
For me it would automate "Keyside room number" (which would be the room from parameter) in my door schedules. Manual is such a pain in the butt when the number of doors is substantial. I'll use the workaround of setting swings to accommodate my schedule and then switch the swing later if needed.
