Thanks for your insight!
I believe B is the easiest to implement, while the assumption is that the KPA is connected to Rig Manager, an easy sync between the two will make either achievable.
For people who have overwhelming numbers of presets, limiting what pops out on the contextual menu shall help. Currently you can't "Favorite" or "rate" presets, though once adding such ratings, you can limit only to have favorites pop out, while others remain silent.
