The feature

Two of my children are recognized as the same person by Immich, and so I've been trying to split them out. To that end, I've tried manually tagging some of the faces as the correct person in the hopes that future pictures match the correct person. But this doesn't fix the existing photos - and because many pictures have both of their faces, using the 'Fix incorrect match' tool doesn't work as only one of the two faces detected as the one person in that picture should be linked to the new person.

Would it be possible to have an option to recluster the faces detected as being a single person (without resetting other face / person information) using the manually labeled photos as the new core matching vectors?
