I think that the easiest and best way to create your own favourite set of tones or style is via User Programs.
In the User Program you can save not only your favourite tone or style, but also the desired effect, split point, arranger setting, etc.
Then, you can make your own page of User Programs and recall them simply pressing one button.
This is better than every numeric input or complicated (and difficult to understand) automatic selection of favourite tones.
