This idea has been developed and deployed to Canvas
I searched through the Community and couldn't find anything similar to this idea...
Google Classroom has only a few good features, one of them being this handy little button when grading quizzes. For File Upload questions that require a manual grade from the instructor, there is simply a little check or X box to indicate right or wrong. You can also put your curser in the box and manually award partial credit. But this little button is so quick! Would really streamline the process of manually grading stuff.
Here's a screen shot of what I'm talking about from Classroom.
