I've validated a route: WOTA1Z WOTAN DCT GAVGO L18 MID UL612 RESMI UN491 LASAT/N0420F290 UN491 BEGAR L15 RIPUS N850 ODINA ODIN7L
The constraint I've put in at LASAT is a requirement according to the route availability document/CFMU. Obviously amend the speed as necessary for your own flight.
Silly callsigns would be welcome as usual. I'll be SAV7707.
