I often lead hikes along courses that overlap or crisscross. On my GPSMAP 64, I could divide the hike onto separate GPX tracks and display them in different colors so I'd know which way to go at an intersection. With courses on the Fenix, they are displayed as one color. Is there a way to make the parts of a hike show up in seperate colors so I don't have to do multiple courses in the watch when the hike tracks overlap?
