But if you don't create the assignment, then it doesn't show up in the calendar, and if it doesn't show up in the calendar (even if it's in 28-point bold font with a date next to it on the main page) then students claim they didn't know there was an assignment due! One can create 'fake' assignment-like pages with the assignment details and then enter an event into the calendar that's not linked to the assignment-info-that's-not-the-assignment-so-it-won't-show-in-the-gradebook, but then you can't have the rubric for grading built onto it because only assignments can have the grading built in, and then you need to turn the assignment itself on at some point and make sure students know to submit there since it'll be a different link than the assignment-thats-not-an-assignment so you'll still have blank grades until the thing's graded, because you can't submit files through not-an-assignment pages. I've tried this and several other iterations.
