Issue with adjusting digital ISO on T3i

[pastatsunami]

Hi, I recently purchased the T3i and installed ML on it. I am finding it impossible to achieve a certain setting that I was able to accomplish on my T2i with ML. On my T2i, when I am in Live View mode and don't have the ML sub menu open, I can press the ISO button and then use the camera wheel to adjust the ISO number including the digital increments like 320 and 640 ISO. I am unable to do this with the T3i. The only way to change the ISO to digital increments is by opening the ML sub menu and changing the values there. I am only able to change the analog ISO values when I hit the ISO button and use the wheel to select. Is there any way to allow selecting both analog and digital ISO increments by pressing the ISO button and changing them with the wheel on the T3i? Any help would be greatly appreciated. Thanks.
