Map View - Default Zoom Range

When we only have one location in a range on Knack, it zooms up SUPER close to that one location to the point where you can't even tell what you are looking at. It would be nice to set how zoomed out (1 mile, .5 mile, etc.) the map defaults to when there is just one location showing.

Does anyone have a solution for this? We are using Google Maps API and it is really annoying that it zooms up so close when there is one entry in the range.
