[Plugin: Basic Google Maps Placemarks] Adding Lat and Long coordinates manually for remote places.

Hi there – Love your plugin. Just a question on editing latitude and longitude manually when a place doesn’t appear. I am marking out a whole lot of surfing spots in the south pacific – your plugin is perfect BUT a lot of the areas are found only by latitude and longitude coordinates. They aren’t known ‘places’ as such. How can I add these manually in the field?
