A more perfect way to switch presets in Scene Mode

Now in Scene Mode, when you push up and down footswitches, it would loading the default Scene of next Presets directly. It would be more convenient if you can change the step of pushing up and down footswitches to navigate through Presets and when you push the Scene footswitches, you can choose the Scene of Presets. Just like the step in Preset Mode.
Besides, please add MIDI CC messages into up and down footswitches.
Time to get me a dedicated volume pedal module.
