Single Table Dedupe "Does Not Match' option for Master Rule
For example, find dupes based on name, address, phone, etc., but then create a master rule to select the records where the Owner ID "does not match" across all records in a dupe set.
It wouldn't work as a mapping type. Since we are generating keys we need an exact match and a non-match wouldn't work. In the master rules it will work as we are comparing each field to a unique value (or in this case to themselves) and since the results set is small and already determined we can have it as a scoring type
