There isn't a feature built into the theme for this, however there is an add-on available in the
AppThemes marketplace called
MapPress which offers a map for listing locations, so you may like to check that out if it's along the lines of what you're looking for. Otherwise, it would involve customization of the default theme on your part, which is technically possible as there is no encryption which would prevent you from making modifications to the theme itself. Thanks.
