POI - FIND - Mapsource - Help please

 

Used Zumo 550 as basic route planner for 6k miles in Alaska last year. Trying to be more specific for our next 20k, so dwnld Harley Dealer POI.
My issue(s); original Mapsource poi has Harley dealers in category "shopping", subcat "apparel". Is there a way to change the Garmin POI category/subcat to "Harley"?
I added the icon and can make waypoints, but wanted to minimize duplicates.
Thanks
