With throttles that have the 'detent' I think it is just a physical feature of the unit and has no input to the software telling it has gone into detent, the game obviously has to cater for more varied hardware and the button is a simple and obvious way to cater for it, I think some game controllers software allow for setting up a 'ranged' controll in the profile setup wher in this case if a slider is pushed into a certain position it will simulate a button press, this might be a way for you to get your desired results.
