Activity tag don't overlap in 2 cycles

[Adele]

Good day,

We have science practicals that happen in a laboratory. There are too many to fit into the lab for the week. Is there a way that I can mark all the practical periods and then say those periods can overlap, but can't overlap more than once in a weekly cycle, i.e. that I can say this week Physics has a prac and next week Bio has a prac.

It can place however way it wants, there are no other timing constraints, as long as there are not more than 1 clash in a weekly cycle between activities with a certain tag.

I hope this makes sense.

Thank you,
Adele

Maybe by using Timeconstraints -> Activities -> Others 2 -> Max simoltanius activities
Select all those activities, select all timeslots and set max 2 simoltanius.
