In (Roll Call) Attendance, there is only possible woth one registration per day. It should be possible with multiple registrations on a single day.
(Roll call) Attendance is not very useful today, since it can't be used to granulate the student's attendance during the day. If a course has a whole day of teaching, it's only possible to register if a student was there or was not there, but what if the student was there the half day? A solution could be to create an event within the Attendance tool, and then tie this event to a date. Then more events could be created with the same date.
