A route is usually a path involving multiple Waypoints.
I don't think a route is visible on the screen until you select it.
Waypoints are always visible on the screen.
If these brushpiles are really long, you could make multiple Waypoints for each one, maybe 3
for each brushpile.
? will denote each brushpile number:
You could name the top of the brush pile Waypoints with a "T" like WP?T, the middle with a "M", like WP?M, and the bottom with a "B", like WP?B.
