Absolutely! This can be done for a whole class or specific students only.
From Assignments & Assessments, click on the assignment you wish to edit.
When the assignment opens up, click "Extend due date" in the top left corner. This will extend the due date for the entire class. If you only want to extend the due date for specific students, click the profile picture for these students before selecting "Extend due date."
Please note: When you extend a due date, any collected assignments will be automatically returned to students to resubmit.
