How do I specify a CC controller for Knob using code?

How do I specify a CC controller for Knob using code?I'm currently right-clicking "Assign MIDI CC" on a Knob, but it keeps getting inexplicably removed, and sometimes it even causes problems with other Knobs.

@CatABC The CC assignment set using MIDI learn is saved in the preset, so when you change presets it will be wiped. You can use the onController callback to direct incoming CCs to knob values, but MIDI learn is usually the best method.
