...the only drawback, it happens sometimes that the user waypoint is not exactly where your circle was and you still see the N/E in the PLOG as it appears not to snap automatically to the created user waypoint. If this happens, simply drag the route point to the user waypoint.
That's why it's probably better to create a User Waypoint as described in my post above. You can get the exact co-ordinates you need from Google Earth.
