It would be a great timesaver for writing instructors and anyone else making many of the same comments to students on assignments to save and store comments in SpeedGrader/Crocodoc DocViewer as one is able to do in Turnitin's Grademark feature. This feature would help SpeedGrader really live up to its name, too.
This idea has been developed and deployed to Canvas
For more information, please read through the Canvas Release Notes (2021-06-19). We're aware that there are two parts to this idea. The "Speedgrader" piece of the request is complete; the idea remains open for DocViewer annotations comments.
