Each week, I have labs and quizzes that open up at different times for different sections. For example, section A might have their quiz and lab become available at 9:10 AM, be due at 11:05AM, and be available until 11:59PM. Section B might have their quiz and lab become available at 4:05PM, be due at 6:00PM, and be available until 11:59PM. Propagate this through the remaining sections, and as you might imagine it gets extremely tedious and cumbersome to repeatedly type. Copying quizzes doesn't seem to be a possibility, at least not with saving due dates and times, and duplicating a Canvas assignment also does not save the due dates and times.
Is there an easier way to do this without having to repeatedly add the due dates and availability times? I teach a rather large class with many labs (upwards of 15 a semester).
