We're a reseller and we want to rebuild the adwords experience regarding location search as seen here:

How do I do that?
I know I can search for locations with the LocationCriterionService, but that appears not to support proximity searches.
I know I can add a Proximity criterion to a campaign, but then I don't get the neat table as show in the image on the right.
(This all became necessary as smaller villages sometimes can't be found in the German area.)
Can somebody help me with that?
