Can you Set a Default Grade With a Default Comment?

Question

Is there a way to set a default grade with a default comment? It is really takes a lot of time to have to individually copy and paste the SAME comment into each student's assignment using speedgrader such as "Good job on this assignment!" Can we get Canvas admin to add this as an option?

It doesn't seem there is an inbuilt solution, it has been requested as an idea since 2016:  [Gradebook] Default Comment - Page 3 - Instructure Community - 375680

But it is possible to do that using the canvas API. Here's one script I generated (with ChatGPT's help) that does the job for Python using the canvasapi module. Note that it requires the assignment id, so if you are using a quiz, you need to get the assignment id for that quiz (different from the quiz id).

You can also select the grade to give the comment to, so you can run it once to give "Great job!!!" for a 10, then once again to give a "Great job!" for a 9, then again for "Great Job..." for an 8, and so on. It's possible to add ranges, or have a dictionary of grades to comments, but I didn't want to over complicate it.
