When you create a morph in CC, you can actually specify whatever range for minimum and maximum you wish.
If you set the minimum to -100 and the maximum to +100, you get a slider with the default position in the middle (zero).
You can also overdrive any morph, positive or negative, by typing the number you wish into the morph box instead of using the slider.Thanks Rampa, but this is for exporting figures with morphs from Daz to iClone via 3dxchange (rather than CC, since the figures have merged geografts)
