Hi @KevinMullin 

You can't select a different policy for late submissions for quizzes and assignments. The policy will be set for the whole gradebook. 

If you don't want the students to be penalized for late assignments, you would need to manually remove the late mark from their submission so they don't get penalized. If you just don't allow late submissions for assignments, you can set the until date the same as the due date, and the assignment will close on that date and they will be marked as "missing". 

Here is a guide on setting up late policy

How do I apply a Late Submission policy in the Gradebook? 

You are welcome to submit an idea to the community for how you would like this to work instead. 

How do I create a new idea conversation in the Instructure Community?
