Managing dates one item at a time is tedious when you are planning an entire semester. This is true for new classes, but also for existing classes since the ability to globally adjust imported dates never works for the way my institution designs new semesters.
I would like a spreadsheet format that shows all date related events on one page. I could then set up all events and synchronize them where necessary. This could be an online form, or the ability to download a csv template and reupload the dates.
I have attached a simplified snapshot of this kind of spreadsheet.
