Editing grades on transcript page

Since our school has been verifying grades and the hardest part about it, is that it is tedious when going through each class for each student. We have unfinalized all of the classes so that we can edit them. Editing their grades on the transcript page would save time and effort. I would also like to mention that it would be cool if, when we finalize a class, we can see their grade in grey letters. This would make it visible to the person editing the grades, and invisible to the students. Please consider this idea. Thanks! Taylor M.
