When multiple files are submitted in a single review and received by the reviewer, there is no indicator showing which files have been opened and reviewed. As a result, when the review involves multiple files, especially when no markups are added, the reviewer may have difficulty remembering which files have already been reviewed and which have not.
Currently, only the 'Submit Review' button is available to indicate that the review for all files has been completed. However, it is suggested to introduce an additional 'Complete Review' button for each individual file to make the process easier for the reviewer.
The current workaround we advise reviewers to use is the 'Comment' function to leave remarks such as "Done" or "Reviewed", but this is not preferable as it requires manual input.
