When grading assignments for a large class when the assignment is like a pass/fail (submitted or did not submit) grade, it would be beneficial to have an option to set all students grades to 100. For these assignments, all or almost all of the class completed it so they all get "100." After selecting this option, individual students grades could be changed for the few that did not complete the assignment. You could also have an option to set all "blank" grades at "100". This would allow grading first the few that did not complete the assignment and then filling the rest with "100." You could do something similar for a Pass/Fail assignment where you could see all the students to "Pass" and then correct the few who "Fail."
This is similar to the request below but there would be no automatic trigger to set the grades:
