Fet already has class card N1,N2,N3 so how can I add a teacher card.
For example, teachers 1,2,3,4,5,6 tag a few periods, teachers 7,8,9,10,11 tag full periods. Then I only need 1 constraint: the card for a few lessons teaches up to 4 days, and the card with full lessons teaches up to 5 days. That way it is much faster and more convenient.
If so, the binding for the teacher is much faster than if I go to create each binding, teacher 1 teaches up to 4 days, teacher 2 teaches up to 4 days, teacher 11 teaches up to 5 days,....
This is already in the TODO (teachers groups), but I added it again, with your name.
Oki, thank you Liviu
