Currently to assign due dates to undated event, you would go to the calendar and drag an exam from the right hand side to the date that its due. But my list of undated event is so long (due to multiple courses) that I have to drag and wait and wait until it scrolls all the way up the calendar to assign a due date. I have to due this for each item that is due. If each course undated event was collapsible and expansible, this would be much more manageable.
