Student Sets Not Overlapping

[satellite2]

Hello again,

We have 4 grades in a department and we want the activities of 1st class and 2nd class are not overlapping (also 2nd-3rd and 3rd-4th). There is a time constraint called "A set of activities are not overlapping" which is very useful for me and I can solve this problem by selecting the relevant activities and applying this constraint. Is there a way to adapt this constraint for the student sets? I mean is there a way to apply something like "1st grade students should not overlap with 2nd grade students" as a shortcut?

I think you can add a dummy common students set in both 1st and 2nd class (same name, and FET will warn you).

That's a great idea, thanks.
