For Latitude / Longitude maps, limit cities shown to only cities in the country of interest

When I create a latitude / longitude map for locations in the US bordering other countries, cities in other countries are prominantly displayed. I would prefer that they not be shown at all, since we don't do business in those countries. For example, on my map of California, Sand Diego is not labeled, but the much smaller cities Tijuana and Mexicali are shown.  Similarly for a map of Northeast United States, I can see Quebec, Montreal, and Ottawa, but very few US cities show up.  It would be nice if these non-US cities could be filtered out.
