Students cannot edit an assignment after submission
Please could an assignment lockdown feature be introduced? Currently, my students can access their submitted work and make changes before and after I have graded the work. It would be much better if as soon as the student turns in their assignment, or I close the submissions, all files become read only and can only be edited by me. This will allow the students to view the work post submission and take on board the feedback, but prevent changes being made after grading.
