Using Courses to add trails to map (best way)? Disable display of course start and end markers?

Hello all,

This is really a two-part question.

I am trying to add trails to the map screen on my edge that are not in the basemap . The way I am doing this is by creating a track in the Garmin Basecamp software or Garmin Connect and then loading the track to the Edge device, Then selecting it in the courses screen and setting it to always visible. This causes it to appear as a line on the map, which is what i want.

Question 1: is there a better or different way to add trails to the map?

Question 2: if this is the best way to add a trail to the map, each course, when displayed on the edge map screen, shows a green circle and Red Square for the beginning and end of the course. Since I am using always-displayed-courses as a way to add trails to the map, I would like just the course line to be shown, but not the beginning and end green circle/red square markers.  Is this possible?
