How to look at/identify a face in the 'merge people' screen?

Hi,

I'm in the merge people screen, and I'm sorting the pictures in order by similarity.

There's a face in the list which I can't identify. Is there any way to open this face up and see what the pictures are that have this face?

I can't add a name to the face to search for it.

I can't click on the face and 'open this person' like you can if you click on an unnamed face of a picture you are viewing.

It seems like the only thing I can do is click on the face to merge it with someone else. Obviously that's not useful in this case.

I have 100,000 faces, so I can't exactly just "look for" this person.
