Feature Request: Missing Assignment Report
If you pull up single student analytics as shown in sample below, this gets us pretty close. Maybe a Tampermonkey Canvancements - Canvas Enhancements could allow users just to see the Sumbissions Section on these pages and then filter for Missing and or zero socres (since some teachers put in zeros - but will allow students to makeup still).? A report showing a whole section of students in a course with missing assignments would still be the best! Or a LTI or even a Google Sheet the teacher could generate per course (making a small number of API calls)?
