You cannot do that directly. You must use some tricks:

Suppose activity A1 (teacher T1, students S1) and A2 (T2, S2) are in the first week and A3 (T1, S2) and A4 (T2, S1) in the second week. Then add in FET one activity, A (T1, T2, S1, S2) in every week. If you need 2 rooms for activity A, add a dummy activity A' and constraint same starting time A and A' and rooms for A and A'.

If you have only A1 in the first week and on the second week nothing, then just add A1 weekly and consider that in the second week it is not taking place.

Please let me know if these tricks solve the problem, if not, I might be forced to reconsider adding fortnightly activities.
