My subjects have their own ID for the sake of our system (I'm talking about few activities with same subject and different teachers). Is it possible to import subject names and IDs? We sometime have two subjects with same name but different ID. Timetable for subjects puts those two in same timetable and adding an ID could solve that problem (subjects' timetable could be composed on the basis of subjects IDs and not name).
It might be possible as a custom version. And I'll add your words in the TODO.
