@RussellStaples -
I agree with what @nwilson7 stated. Having a way for Canvas to automatically label all unscored responses as missing after the due/until date would be ideal - I could see some possible issues with it though.
However, I interpreted a possible solution to your question more along the lines of is there a way for you to assign a label of missing (the red shading)to all assignments not turned in (i.e. there is no grade for the student in the grade book). Basically what is available for setting a default grade (which has to be numeric) but for the missing shading.
I checked out the gradebook because I knew EX was used for excused. Unfortunately nothing is used for missing or late. So you can't just export the gradebook and put in the missing designation for all the missing assignments (what I was going to suggest was set the default grade to -1 for all unsubmitted work, export the gradebook do a replace of -1 with the missing designation and then import the information back - however, that is probably more time than going through the assignment manually).
Having the ability to set a default status of missing, excused or late would be nice in addition to the default grade.
