IPTC keywords –> WPPA tags

This may be here already but I couldn’t find it.

I have photos with IPTC keywords in them.
And I have photos to which I have added tags within WPPA.

But ideally I’d like the IPTC keywords to appear in the WPPA Tags field
so I can search on them.

Can this be done other than manually ?
