Copying "Region Person Display Name" into the fields "Last Keyword XMP"

[Groofertje]

First thing for all, a BIG compliment : It is a wonderful product, thank you, Phil!!

I have a stupid question,

I have tagged all the familyfoto's i have (there where a lot )
I have also inserted the display name in the subject tag so my media-server can retrieve the foto by individu.
Of course after the work i have forget to fill some of the display-name's into the subject tag

Is there a system to batch changing the XMP data so the "Region Person Display Name" is copied into the fields "Last Keyword XMP" and "Subject"

With other words the the fields "Last Keyword XMP" and "Subject" must be cleared and then copied with the information of the "Region Person Display Name" so they match

The file's are in the folder "Foto" and in the sub-folders named by date. The rest of the meta-data must be unchanged.

Thanks a lot

BTW, sorry for my poor english

Sure:

exiftool "-lastkeywordxmp<regionpersondisplayname" "-subject<regionpersondisplayname" -r c:\Foto

This will clear LastKeywordXMP and Subject, and set them to the same as RegionPersonDisplayName (if it exists).
