GemWeb Plus Reports

Anyone have insight on if/how to generate better QC reports out of GWP?  I know there's the PDF report for CVP and instrument iQM, but we were looking to calculate SD/CV or more of a Levy-Jennings type look for an audit.  Does anyone have insight while I wait on my Werfen folks to assist aka tell me no (again). I hate not being able to trend month over month to compare the instrument or see shifts on the instrument without copying and pasting into another format.
