I plan to format my quizzes in this way quite often (see screenshot), but it is time consuming to enter in the various due dates/times for each class period, especially for my course with three different sections. (I do want to have those due dates/times vary per section since it helps me monitor on time vs. late submissions.)

 

I was hoping to be able to duplicate this for the future and just change the name of the assignment and dates (times for each section would stay the same) to make things easier. But when I duplicate an assignment, only the directions from the rich content editor are retained. The information for sections/dates/times drops off. Is there a way to work around this? Thanks in advance.
