Describe the enhancement and the motivation for it.
Something that would be nice is to be able to select the files that are part of the review after uploading or generating a diff.

When generating a diff all files are part of that diff, including project files and configuration files that do not need to be reviewed.

It would be nice to be able to select the files that should be reviewed after a diff is uploaded or created, so the size of the review is reduced and unneeded files are not reviewed.
