Scott,

Won't this do about what you want ?



Edit:  Seems like it would work but could not see any results.  Perhaps I don't understand how it's suppose to work.
Edit 2:  You have to select 'SNR Strong decodes' or 'SNR Weak Decodes' (I was using "all decodes") in the 'Panels'.  The "threshold" you select picks the dividing point.
