Mac Photos Add Face

Hello! I use Mac photos to catalog lots of pictures. I do this by using the "Faces" feature of Mac Photos. I was hoping to use KM to do something but can't figure out how.

If Mac Photos recognizes that a person's face exist but says "unnamed", I already use KM keyboard shortcuts to send the person's name to tag the face.

However, in the case that Photos does not recognize that there is a person's face that needs to be added, I need to add the face frame first, then name it. The only way I know how to do this is to mouse click "add a face" from the "get info" box. Given that the location of the get info box can float around, how would i do this in KM?

Help please?
