adding pages/controls to a 2023 classic with the 8.4

[c69ss396]

I have a new 2023 classic, I've add several things so far such as push to start, Aux switches, power tow mirrors and brake controller. The one thing I haven't been able to do is add anything to the radio. Did they change something because on older 4th gens I could add performance pages, controls for the aux switches and controls for other accessories added.
