I have found numerous references to creating custom categories with POIs, but I would like to create custom Favorites in specific categories. I can load my custom Favorites by placing a Temp.GPX file in the Garmin/GPX directory. Is there a way to specify what category those new Favorites will be in, other than editing them once they are loaded in the unit? I already have various catgories under Favorites, and would like to add new items using a file. I am using a 765T.
