It's barely mentioned in the manual, "By right clicking on any model displayed on the gear view you can choose to save/load a preset related to only that model or copy/paste its setting to/from another model." and I guess I didn't realize this is different from a Preset.

If you haven't tried it, this is a great way to dial in an amp or a mic setup and use those settings across different Presets. You don't have to create a whole new preset just to save knob settings.
