Have you guys at Reiza considered this, either for AMS or Reiza17? Having so many more options these days I'm finding myself wishing I could simply have a unique map for all the cars. For the V10 you need a TC and autoshift level bind as well as a TC override bind AND Launch Control. For FReiza and Extreme you need a DRS button and I assume more once you update KERS. For V8 Stock you need the boost button and the ARB. It goes on. I've got a DFGT which means I have a fairly good number of keys but its still not enough if I want to include the Brake Bias, HUD controls, analog clutch, glance buttons and neutral button. Obviously there are ways around things in my controller software as well but it'd be a nice feature to have.
+1, but we've been needing this for 10 years since the beginning of rFactor. Maybe Reiza will perform a miracle?
