Is it possible to integrate the googlemaps plugin with Directory custom field?

I've set up a custom field in Directory for the address of the venue being listed, and just wondered if the map can be coded to show automatically rather than having to manually create it and insert it into the listing.
I don't have a problem adding individual maps, but when I open the site for registrations it would be good if the map can show automatically as otherwise it could take a while to update the listings (I'm hoping the directory will be popular!)

Thanks
