I have made my Airio rotate new Westhill tracks. You'll need to add the new Westhill Configurations to your Airio.tcd.txt file, then !rld.
Basically, these keys should have all of these values:
TrksList=BL1 BL2 BL3 SO1 SO2 SO3 SO4 SO5 SO6 FE1 FE2 FE3 FE4 FE5 FE6 AU1 AU2 AU3 AU4 KY1 KY2 KY3 WE1 WE2 WE3 WE4 WE5 AS1 AS2 AS3 AS4 AS5 AS6 AS7
TrksName=GP Track, Rallycross, Car Park, Classic, Sprint 1, Sprint 2, Long, Town Course, Chicane Route, Club, Green, Gold, Black, Rallycross, RallyX Green, Autocross, Skid Pad, Drag Strip, 8 Lane Drag, Oval, National, GP Long, National, International, Car Park, Karting, Karting National, Cadet, Club, National, Historic, Grand Prix, Grand Touring, North
NoReverse=BL3 AU1 AU2 AU3 AU4 WE3
NoPitlane=BL3 SO2 SO3 FE6 AU1 AU2 AU3 AU4 A13 A14 B21 K21 F24 WE4 WE5
