Reply to Custom fx presets

Hey djtt. I was wondering if anyone knows how ean made fx presets in his new mapping (by holding shift and double clicking a button). I want to make the four fx buttons under the knobs work in a similar manner, enabling 4 different fx group settings assigned to them that, when double clicked, will enable the fx and set the knobs to the desired positions. I tried recreating it in the midi editor but it didn't work. Thanks guys and gals
