lab lesson to room1 or room2 or room3

[dimzev]

A lab lesson from a group can be done in room 1 or room 2 or room 3
and this happens for others groups and more rooms ....
How can insert this choice to FET?
Thank you!!!

By using roomS constraints.
It's a bit depending on your dataset. I wrote some examples in the follwoing link. Maybe read it and ask again if it still unclear:
