Bulk editing EXIF data (GPS and dates)?

Hi,


Some of my older photos do not have EXIF data in the form of dates and GPS.

I would like to add approximate dates and GPS location to these photos.

I can do this from command-line using exiftool However, it would be 
easier to pick and choose images using the DK GUI.

Is it possible to use DK to bulk add/edit EXIF data?


Note: I only want to do this for specifically chosen photos - I do not 
want DK to generally start modifying EXIF data on photos in my collection.
