You have choice to display as EEP, EXP, ETP1, .... or simply WPT1, WPT2, ...
First at the end of LEGS page, add any waypoint (EGKK i.e),don't worry, you will delete it at the end
Enter in the scratchpad geo coordinates of ETP1 and put it below EGKK, WPT1 is created.
Enter ETP2 geo and put it ON WPT1, it will create a discontinuity between WPT1 and WPT2 automaticely
Same for EEP, EXP,....
You should see :
EGKK
WPT1
-------
WPT2
--------
WPT3
-------
etc
Now DELETE EGKK and EXEC
Check on MAP, these new WPT are on the route but not active (here but not magenta !)
That's it
The nice way is to name your waypoints ETP1
pr EEP, .... in the NAV DATA page and to recall them with the same way in the LEGS page
Using it on every etops flight
last, in FIX1 page, as you should put your ERA1 , choose /420 ou can now cross-check your EEP and EXP...with FIX page 2
Enjoy
