Am I correct that quizzes in Canvas have much less functionality than assignments? As far as I can tell, quizzes do not accepts file uploads of more than one image per question, and they do not allow you to use the document viewer to annotate, comment, etc. Why is this? I imagine many, many teachers want to write on exams and quizzes. I'm teaching online for the first time and now I want to go back and rebuild every quiz as an assignment. Or, am I missing something?
