We have 25 periods a week now and some subgroups only have 21 or so periods a week - so they have some free periods during a week.
How can I force certain days to be full and others not, for example, I want them to have no free/off periods during a Monday and Wednesday.
Is there a way to accomplish this? I don't want to place activities during fixed times as my timetable has trouble building then, but any activities can be placed during those days.
Thank you.
Activities occupy min/max time slots from selection.
