Dumb question from a Mark II user. Because we only have Bank A,B,C without any space for our own presets, any tips on how/where to save my own presets before I import the factory ones - as I presume that would overwrite anything I have currently in banks A,B, C? I suppose I would then delete the factory presets I don't like and then import my own once that is done (that is a little scary LOL)?
