I'd like that feature also. From what i've seen it can't be done currently. The only way to prevent overexposure/blown highlights is thru the use of the histogram. Maybe sigma can address this in a firmware update. I emailed sigma with a request that this be done in the next firmware update. If everyone with a merrill requested it perhaps they would do it.
