It would be great if this could take a register for us (who is on GC and who isn't)

I use several other programs that are not synced with Classroom, but allow "download grades to excel". I was hoping to find something that would quickly transfer the grades into Classroom. It's a little slow, so it does not save that much time, but that's ok, because it is more relaxing to watch the program work than type in the grades. Also, sometimes I like to upload the grades before the due date, just to get some grades in. And then upload them again when more students have completed the SAME assignment. Or sometimes the online assignment is completed in "waves" (absences, redos, etc....) It would be nice to be able to overwrite instead of have to recreate a whole new assignment, and have to delete the other assignment. It would be cool to have the option to not have to delete the first uploaded assignment. Each time you upload grades from the same assignment, you need create a new assignment name, even though you just want to update the grades on an already named assignment. So it would be nice to add a feature "Change/overwrite grades on an already created ImExClass Assignment?" And then list all the ImExClass assignments for that class in a dropdown menu. If it could do that, then I would use it frequently.

Is there a way to update scores that are currently in the Google Classroom directly from the Google Sheet? I have spreadsheets of data from external sites and I want to use these to update student scores in the Google Classroom as students submit work. It would be great if existing assignments could be updated instead of creating a completely new assignment posting (and deleting the non-updated one). Otherwise, the features are great (a zero must be written in on any empty row for this to work though).

I agree
