How do you update the hz_parties.party_name via apps?

In the Customer Standard, there are some customers where the customer name (aka party_name) is not the same as the individual fields person_first_name and person_last_name. I have confirmed that the record is from the HZ_PARTIES table, and that the party_name does not match the person_first_name + person_last_name.

Example: party_name = John Smith; person_first_name = Jane; person_last_name = Smythe

For these records, it is the party_name that is incorrect. Is there a way to update the party_name through the apps?

I attempted to change the party_name through Customers Summary, which did make the change, but then the number of match results in the Customer Standard doubled.
