After merging all actual duplicates it would be great to be able to Select All mark all remaining duplicates "Not a duplicate" in bulk.

We have a lot of name only matches (we only have a first initial for many donors) and we require at least two pieces of unique information to match before merging so all of these need to be marked not a duplicate. We keep duplicates at zero but when records change it re-searches them - someone recently updated the records of a Smith, a Jones and a Brown and suddenly we had 40 possible duplicates that were name only matches so not enough information to determine if they were actual duplicates.
