Hello @lorraine_carey,
Thank you for reaching out! Unfortunately, there isn't a way to do this once you grade the submission. The average in the speedgrader is calculated from the graded submissions; you marking a submission with a zero is grading the submission. If you don't want the submission to be calculated in the average, then you will need to leave that submission un-graded. We are so sorry for the inconvenience.
While this may not be possible at this time, we will also recommend that you leave any suggestions for improvement here.
