Category Filter – Display Map Pin to match with Category Filter when selected

Looking to change the map pin that is displayed for a directory entry that has more then one category associated with it.

Example:
Place (Directory entry): Extra Toppings Pizza
Associated Categories: Restaurant (default category), Delivery, Food

When user selects the category “Delivery” GeoDirectory displays all Businesses associated with the category “Delivery”. The map displays the default map-pin for the Business (which in this case is Restaurant).

Need to display the matching Category map-pin when the associated category filter is selected by the user.

RE-CAP
Example – Extra Toppings Pizza (default category Restaurant )
• User selects “Food” Category – Map displays Food Category map-pin on results page
• User selects “Delivery” Category – Map displays Delivery Category map-pin on results page
• User selects “Restaurant” Category – Map displays Restaurant category map-pin on results page

Thank you for you time and awesome plugin!

** We would also like to display all associated category map-pins in the Search results grid and on the individual entry page (which currently displays text links for category using Supreme Directory Theme). Should we be using a different theme (e.g. GeoDirectory Framework (GDF) ) Thanks again!
