Thank you for considering this.
And yes, I suggest adding preferred room(s) for activity tag(s).
Thank you,
Catalin
PS. Regarding your q. about other constraints - I have to try to see if for our subject called "Foreign Languages" we could use FET (one main subject - Foreign Languages - is split in several languages - English, French, German etc which get their rooms with their own teachers. Each language has students from several years/study programs or groups/sub-groups)
You have 2 methods:
1) Make overlapping groups. For instance, if you have year Y1, group G1 and subgroup S1. Subgroup S1 has English and French. Then add group G1, containing subgroups S1 E and S1 F. Add GROUP S1 (contains S1 E and S2 E) and consider it as a real subgroup.
Please ask if something is unclear. I am a bit tired, I might be wrong a bit.
Please read about overlapping groups in help.
2) add dummy activities (no teacher, no students), same time with A (TE, TF, S1). Preferred rooms of these dummy acts. are as needed. They take care of occupying the rooms.
Thank you for answering. I will take a look at the 2 methods suggested above. One more question: is there a possibility to have a constraint the forces two or more activities to be hold at the same time but in different rooms?
e.g.: Activity English for some students has the same hours as activity French for the same students (maybe the same students - because students from sub-group 1 are split for 2 or more different languages)

2 clarifications (warnings - you did not understand correctly):
1) Each activity must take place in a single room, which must be free at that time. You cannot have 2 activities at the same time in the same room.
2) Each activities which have common students (subgroups) cannot take place at the same time.

this is correct.

then how could I divide my students? For now the students are split in 3: year of study, study program as Groups and Group Number as sub-groups because seminaries/labs are done at sub-group level (except foreign languages where a language gets students from more that a group or sub-group). In this case (foreign languages) it would be nice to have them at the same hour.

I told you, but I was in a hurry and my message was not clear enough.
Suppose you have year Y1 ( G1, G2 ). G1 (S1, S2). S1 and S2 are divided by language (E, F, G). Then define in FET: year Y1 (G1, G2, S1, S2), group G1 (S1E, S1F, S1G, S2E, S2F, S2G), group G1 (as needed), group S1 (S1E, S1F, S1G), group S2 (S2E, S2F, S2G). Use in activities FET groups S1, S2 and/or subgroups S1E, S1F, etc.
Some real subgroups become FET groups.
Is it clearer now?
