Set the date on multiple selected photos to a hard value, not a delta?

Thank you, I’ve mostly jiggered my current batch of photos into correct dates using photos. It meant every time I tried to correct about some fraction, and I said I was very selective about the fraction would be made less accurate, but back-and-forth I have pushed most of them to the correct date. I will try this with the next batch I import, or if I find a large chunk in this batch still needing a simple date set.

UPDATE: Talked to Apple Customer Support. Confirmed this is not possible. I'll submit it as a feature request.
