Is it possible to have an override in the bulb ramp menu for max ISO while in bulb ramping? During normal shooting, I occasionally go up to 1600, but during time lapse, I have perfect exposures at 200, but the bulb ramping sets it over 1600 to 3200 and grains out my images. It seems a bit out of the way to have to go through the regular Canon menu to set it before time lapse and then reset it when I'm done.
