[Feature] Reassign entire face subcluster when reassigning a face from side pane

The feature

This one is a bit complex, but The-Software-Which-Should-Not-Be-Named does it quite well, I think. Or Apple Photo, I can't remember which.

The idea is that whenever you correct one face on one picture, it does not only correct the tagging for this picture, but for all other pictures that were in the same preliminary cluster before being merged to the wrong face.

Example: I have all the Christmas pics of every year, with all the same family members. Each event has more than 50 pics. Yet, this year, there's a new cousin at the table. Since kids are easily mistaken in face recognition, the new kid is wrongly clustered under the name of the kid that was predominant in the past years (the unbalanced cluster effect).
Now I would like to be able to start from one pic of the latest Xmas eve, reassign one face of this cousin, and all the other faces are automatically corrected.
How easy is it to implement?
