I'm looking for a solution:
I have differents groups "school A", "school B", "school B", ...
These groups should choose through the module "choicegroup" the groups "workshop 1", "workshop 2", "workshop 3", ... , "workshop 90".
In order to obtain a mixture of students from different schools, in the first week only a maximum of 3 (for example) students of each school (eg group "school A") can choose a specific workshop (eg group "workshop 2").
In the second week, this restriction should be canceled either manually or automatically.

It would be good if this would be possible via a user profile field (eg "school A".

Is there a possibility and by when?
