I see what you mean, an option for ISO shift along with the existing Tv and Av shift for green button programming. Good idea, though I am not sure how the program line would be defined for that case for other than stop-down metering. (Auto-ISO is currently strictly unavailable in M mode* even with A-contact lenses, probably for that reason.)

* I know, some bodies fail-over to TAv for that case, but that is not the same as green button metering in M mode
