Buddypress Profile Mapping - Can we hide their house address for privacy reasons?

Hi

The Google Maps plugin + buddy press user profiles is mapping perfectly. Well done !

However, if the user enters their street name in the specified location field, in their user profile, the world can see which house they live at.

Is it possible to only display their suburb, city and country - yet still display an accurate location of the avatar on the map?

See here for what I'm talking about:
