Hi Dan,
While I also quite like the idea, I am nevertheless going to have to disappoint you here, since this would interfere with the way the software stores Presets (default ones on top, additional ones below).
To paraphrase the PawnStars meme: “Best I can do is this hack trick” - which allows a user to transfer added Presets to the default location, and, upon closer consideration, perhaps also allows for the inverse (to transfer default Presets to the location where additional Presets are stored).
But, I haven’t tested this second possibility yet.
I should also conclude by emphasising that messing with these settings is done completely at your own risk.
