5D3 - Custom function button glitch??

By default, the SET button in the center of the main dial has no function in shooting mode. I decided I want to change that and assign it the ability to adjust the ISO. So, by holding the SET button and scrolling the small wheel with your right index finger, you can instantly adjust ISO. Not necessarily a ground-breaking feature, but for me it's easier than finding that tiny ISO button on top of the camera.

So the issue is that if you are operating in Auto ISO, and you use the SET custom button to change the ISO for a shot, you can't get it back to Auto ISO. The selection stops at 100, forcing you to manually set things to Auto using the default method. I can't imagine this is something that was purposely done by Canon.

Again, not a major fault, but it would be nice to get it corrected.

I've not noticed that before but I tend not to shoot with auto ISO.

I'd like to see a change where the scroll wheel is continuous. I'd like the option to scroll forward through the highest ISO to the low end again and vice versa, same with shutter and aperture.
