You're welcome. Bottom line, at least feed the preset machine two images at the extrema of what your auto ISO range is (to avoid clamping of the sliders in the preset at the highest specified ISO). Better yet, if you find that the interpolated slider values are not exactly right, fill in with some additional ISOs and slider settings that work better for your camera. Then you can steer the interpolation in the direction you want.
Have fun!
