Distance / Proximity exposed filter default location with "Use map" input

Thanks for this great module. i am now using gmap Distance / Proximity exposed filter in a view to search for the nodes. currently i set the origin using the Latitude / Longitude input (use map) option in the filter setting as shown in the attached picture.

is there anyway to set the default marker of the exposed filter map so that it will use the user location or even it could detect the user IP and set the default location. I think this will be a great feature.

Thanks.
