How to recreate location Pins from GPS data

Hello, I made a big mistake in my catalogue. Accidently I added a new location to all of my pictures.

As I detected my mistake I deleted the Pin and with that all assigned location information.

Is there a possibility to redo the automated detection of the location based on the GPS data as made during the initial import of the photos?

A reimport is not working. If I delete one photo out of the catalogue and import it again the location and Pin are added again.

Any ideas?

Best Regards

Frank
