Wow I didn't know this! We're all very accustomed with the NG series for obvious reasons and that was obviously and unfairly my reference when assessing those red lights. Thanks for the info and thanks for incorporating it into our beloved IXEG!
If it is a coded into the sim, this is how it works on Garmin:
1) Go FPL page
2) highlight fix you which to hold at
3) Press MENU and then HOLD AT WAYPOINT
4) Enter prefered INBOUND or OUTBOUND course and LEG TIME.
Ignore EFC (expect further clearance, it's just a helpful timer).
