When adding a named guest, only 3 "top" possible duplicates are shown, and instructions are provided to add more information to narrow the list. I know which relationship record I am searching for, but there is no additional data available on that donor, so I am unable to connect the relationship record as the guest because of this limitation. Instead, allow the full list of possible duplicates to be shown, to ensure that all relationship records are visible, regardless of the current data available for the donor. (Also, I tried putting in a random birthday on the record I needed to narrow the list, and it still pulled every result hidden behind the first three records.)
