When saving a route as an overlay, or .GPX file it would be nice if you could name that overlay something meaningful instead of just the name assigned to it (ie. I-57 to I-24 244 mi.) I found a workaround by editing the file named: maps-pro-overlays.json , but this shouldn't be necessary.

As a new user, this would be a big plus in understanding and using your overlays.
