user defined function?

Does anyone know if the new prius V have a way to user customize a function and program it to a button on the wheel.

For example I would like a button to begin glide at any speed and remain gliding until touch either gas or brake pedal.

Is that possible, seems toyota website only talked about vehicle information with customizable settings, but not letting user customize or reprogram buttons on the car or on the wheel.

 

By glide I do mean coast, pluse and glide (also called burn and coast) is what people call it, since this will be my first hybrid, I am learning new terms all the time myself.

Coasting is most efficient when the engine is not running, from I read online so far, in a prius if you taking one's foot off the gas, the car is not coasting, it will slow down by regen to battery. In order to coast, driver have to manipulating the accelerator (by pressing down just enough) to make the car coasting. Also if your speed is beyond certain number, the engine will not shut off (in coasting)

So if toyota let us program a button to start the coasting (and remain in coasting until we either hit the gas or brake will be very helpful). Say you are 1 mile from the highway exit, you can just hit the coast button, engine will shut off, you will just coast from 70 mph to 60mph. Or if you see a red light far away, you can just coast down from 55mph to 40mph (and hit the gas again when light turns green).

So a coast button on the steering wheel is much easier to learn and use than to try to just give enough gas and watch all the arrow shut down on the display. (So I can spend more time pay attention to the road than the colorful display)

Please feel correct me if I am wrong. (like I said, I am new to all this)
