AFAIK you can't "double bind". I'm not an expert though...
However, you could make more than one Control Profile. I do that on both rFactor and Race 07 as they both have many different cars that use different gear-change-types (H-Pattern, Sequential Stick, Paddles). This means you can just switch your control profile. I own a G25, and I have many different Profiles:
For rFactor:
G25 - H-Pattern & Paddles
G25 - Sequential Stick
G25 - WRC Configuration
G25 - WRC H-Pattern
G25 - Historic GT
PS3 Controller
Keyboard (for Testing)
For RACE 07:
G25 Paddle Shift CUSTOM
G25 Sequential Shift CUSTOM
G25 H-Pattern CUSTOM
In both games it's pretty quick and easy to switch between the different configurations in the garage (just a few clicks).
Also, in rFactor, you don't need to re-do the whole controller profile. You just make any necessary changes to your existing controller profile, click "Save" and then save it under a different name
So, AFAIK, that is the easiest solution.
