Beakybird,
With Korg arrangers you can go into arranger preferences and have the fill 1 or 2 button go to any variation you like or just have it go up one with each press of the fill button or down 1 with each press. Or, if you like you can pick a variation you wish to go to everytime you hit either fill 1 or fill 2.
