A new trick
The following is a method to create visible points on your Navigation Display, without messing up the waypoint sequence of your oceanic stretch. The method works on B-767 FMS, try for yourself whether this also applies to more modern Boeings or Airbus FMS.
Be sure to complete your route to destination with an approach, then AFTER THE LAST WAYPOINT OF THE (MISSED) APPROACH, enter a (any) waypoint, then the ETOPS Entry Point, then a(ny) waypoint, then Equal Time Point 1, then a(ny) waypoint, then ETP 2, … etcetera … until a(ny) waypoint, ETOPS Exit Point – then DELETE ALL THE A(NY) WAYPOINTS, then EXECUTE.
In that way, you will have, after the last waypoint of the missed approach, a sequential string of discontinuities and ETOPS significant points.
The route calculations (ETA and predicted fuel at destination) still get calculated without disturbance, the ETOPS point show up as non-active waypoints on/along your route and the Oceanic Waypoints are not disturbed for ATC purposes!
The temporary a(ny) waypoints are needed to create the discontinuities. As identifier you can use any easy identifier that actually exists in the NAV database, e.g. AAA or BBB or CCC.
The insertion of an approach is needed in the route, because otherwise the added waypoints will be included in the route to destination.
