Not sure I understand the question. The map works quite well!

I think what I would probably do is
* with a map click,
  - snap that to a road
  - add the point to an array of locations
  - remove the entire directions overlay
  - add a new one from the array of waypoints

You could then implement a mechanism of removing points from the array
(say by clicking a marker to make it disappear). Having removed the
point from the array, remove the directions overlay and use
loadFromWaypoints to create a new one.

Inserting a point into an array can be handled similarly, say by using
a right-click on a marker to indicate "insert next point after this
one". Having inserted the point into the array, remove the directions
and use loadFromWayPoints to create a new one.

The maximum number of waypoints is 25, but that's probably reasonable
in this case.
