I am primarily using the Google Cloud Assignment feature for my students, but when the due date passes, Canvas is not marking these assignments as missing. If a student submits after the due date, the assignment is marked as late, but I have to manually go in and mark any assignment without a submission as missing. This is a large waste of time, especially with 150+ students in a virtual setting, and it's compounded by the fact there is still no shortcut in the grade book to mark missing assignments.

Is there something I'm missing? Is there a way for Google Cloud Assignments to be marked as missing if they are not submitted by the due date?
