I agree. This is common even in Basecamp. You can easily change between a "shaping point" which does NOT announce and a "waypoint" which does announce. But you have to go through the waypoint or it will keep trying to re-route you BACK to that waypoint that the system thinks you missed, where the shaping point lets just blow by and on to the next.
In my VERY LIMITED experience with MRA we create "shaping points" in Garmin parlance.
