Break for a group but for others not...

[sunnyengineeer]

Im creating time table for Second, Third and Final year of engineering.
Third and final year have requested for break off..i.e continuous hours means early day off...How to do this..means we can induce break but that is for all the groups, but this group is different...and also many faculties are teaching in different years, so I cant make a separate Time table...

I think you can use constraint students set not available.
