Activities assigned to fixed times on different days

[mah]

In my university, activities are assigned to fixed slots each day (https://www.iitm.ac.in/timetable), possibly to distribute un-preferred times among teachers. Thus, a class (activity) assigned to the A slot happens from 0800-0850 on Mondays, 1300-1350 on Tuesdays, 1100-1150 on Thursdays, and 1000-1050 on Fridays. Similarly for the B, C etc slots.

How do I feed FET these slots?

Thanks in advance for your help.

i suggest to use "A set of subactivities has a set of preferred starting times".
