Currently, you can upload multiple files as a "folder" and get an initial review on them - but if one file is approved and the others require changes, the next round of approvals does not track the approval on the file that was approved. Essentially, you have to review and approve each file every time rather than only approving the files that required changes.

I do like that all files in the folder are listed in the approval round, but it would be very helpful if approved files stayed approved no matter how many rounds of review.
