Highlight changes

Working on a neighborhood with already pedestrian and one way streets, it would be useful to highlight when a street segment has been changed/touched.
This to see what needs to be changed from the initial state to get to the"desired" state. Especially if for example a one way street needs to have it's direction reversed.
Maybe by "just" making the arrow or modal filter bolder (even though that would help if we were to remove a restriction).
Or maybe it's possible to "bold" the street segment without impacting the shortcuts "readability" ?
