Currently, there is a way to individually select q&a pairs to be excluded from content cleaner, but there is no bulk option.
Also, a couple of clients in the last 24hrs have also suggested the capability of when working in the duplicate report to have the ability to hide certain "duplicates" altogether rather than from the screen they're currently working on. So, not have those potential duplicates come back into the report. There are certain pieces of content clients use that might show as a "duplicate" but technically are unique so clients want to have a way to "keep" these pieces of content in the library and have them pulled from the report and a suggestion was to simply be able to exclude/hide them entirely from the report itself.
