Is it possible to adjust front focus in K100DS


I don't think so but I want to ask to make sure. When pixel peeping testing my DAL 55-300 wide open in my K100D Super I notice that focusing is ever so slightly off by a hair. It is not a big issue and I rarely shoot wide open. Stopping it down ever so slightly pretty much solves it. But I think it could benefit from a hint of front focus adjustment.
I've heard of such adjustments in other models but I don't think it can be done in the K100D Super. Is that correct?
More curious than anything else.....

You can make a global adjustment in debug mode, or you can send in both the lens and the body to Pentax for individual lens calibration (not every service centre is equipped for this task however). The story I have read is that Pentax bodies could store up to 3 (or 4?) lens AF adjustment, and my recent experience seems to confirm it because my K-m only had BF with one of my lenses and Pentax Canada were able to address it properly.
