Hi, I have a question about the Canvas gradebook.  The gradebook used to have a button called "treat ungraded as zero," which would show a student's true percentage score, in the event that the student did not submit a quiz or an assignment.  Without selecting "treat ungraded as zero," the gradebook shows an overall percentage score of only completed work.  In any case, Canvas seems to no longer have "treat ungraded as zero," and I'm wondering if it is buried in Canvas somewhere, or if there is another button that performs the same function.  Thanks for any clarification you can provide!
