Add Button To Disapprove Files

Often times our design team presents several drafts/concepts for a project, some of which are not approved to proceed in any way. It would be super helpful to have a button with the option to "disapprove" rather than the reviewer needing to add a comment to say "not approved." The comment then automatically triggers the text "changes required" applied to the file, which isn't true because there are no changes needed. We just want to completely reject the file altogether.
