One thing that I think would make managing presets a lot easier would be a Replace All function for devices. Suppose I create 30 presets all with the same amp device and after a month or so I realize I need to tweak it by adding more treble. It would be great if there were a Replace All option in the device menu that would allow me to make that tweak and then apply it to all instances of that device across all the presets that contain that particular device. As of now, if I need to adjust a device, I have to Save Setting as Default and then go through every preset manually to replace the device if I want to keep my sound consistent. This would make the experience much more akin to using an actual amplifier for example.
