CarPlay steering wheel control

I bought a vehicle without Sirius xm. I use the app to stream music with CarPlay but there is no way to change stations with the steering wheel buttons. Instead, the steering wheel “next” button bring you to the next track , but not the next radio station. It would be very helpful to add this feature because swiping on the touch screen to get to the next station is much more distracting than simply pressing the next button on the steering wheel.
