Map summary overlapping segments change colour

In either the Companion app or the main app whenever you get a map summary of the route you just completed any overlapping map segments should change to a different color so that you can see where you’ve been. For example if you do a short loop multiple times and then look at the summary all you see is the same color with no evidence of how many times you did the loop. I would think it would be easy to have the map change color when it starts to overlap a line it’s already been on. Does that make sense?
