Do EFI live tunes with the 5 click only work with presets or can they be modified?

Im only curious because I bought a truck with what im pretty sure has EFI live on it (with the 5 click knob) but im not going to turn it past 1 until I know what the tunes are.

Any help is appreciated.

Also - I live in NC/SC if anyone local can help. Glad to drive to a shop.

Truck: 2015 Silverado 2500 HD LTZ LML
