Scott,
The micro arranger does store styles individually. all you do is go to the set that has styles, push open, select the style folder, push open, select user1,2 or 3, push open, select the style you wish to load, push load, it will now give you the choice to load it to any of the 48 locations, push load and you have loaded 1 style. You can do this for all 48 locations and then save as a new set and there you go!
