Hi @drcolquitt,

Unfortunately, I don't think you'll be able to do this as a single bulk acton in Canvas.  There is a way to bulk upload feedback on submissions, but that won't be compatible with peer reviews.  If your institution has the permission enabled for your role, you can use the recently released feature to submit the original papers one by one via the submit for student link.

As an alternative, you could investigate whether your other in-class system has an integration with Canvas available, which may negate the need for the manual step of getting submissions in Canvas.

I hope this info helps, even if it's not exactly what you were hoping for.
