Instead of a solid line, have footsteps or other line type as an option.

Sometime to show an access or path of travel for my workers or project manager, I would mark out.
Having it as an linear option lets me add calculations to the travel as well. Maybe a roll off box is across the parking lot, and have to go through a certain route to get there, I can add a formula to give me an idea of how much time it will take to get there.
