Teacher's Meeting in defined time, counting as activity

[massari]

We have two Teacher's Meetings on Wednesday and those meetings occur in the following times: 10:40am and 11:30am (each one lasts 50 minutes).
Some teachers attend the meetings at 10:40am and again at 11:30am. Others attend only the meeting at 11:30am, depending on the number of classes they have during the week.
The teacher "Luiz C" attends both Teacher's Meetings.
How can I create those meetings in FET, and tell FET that the teacher "Luiz C" attends the two meetings, and those meetings are counted in the total of activities of the day, not exceeding the limit of nine classes? Teachers in our school can't have more than 9 classes in one day.

I need help!
Thanks!

If I understood right: Why can't you add a constraint teacher Luiz C max 7 hours daily?

Thank you Liviu.
If I could apply that constraint only to Wednesdays for a single teacher it would be ok.
Trying to manage this situation, I apllyed the constraint "A teacher not available time" (see image below), but I think it is not the best way, because it reserves the time for the meetings, but it doesn't count these times as activities.
I'm never sure if I make right this situation for this teacher and not cause the same problem to other every time I generate the timetable.

I am not sure I understand correctly, but to add a constraint of max hours on Wednesday for teacher T you can add a constraint activities occupy max time slots from selection, selected slots = all from Wednesday, max occupied = 7, activities = all activities of teacher T.

Please let me know if this solves the problem.
