We have recently upgraded from Openlab Chemstation edition to CDS 2.4 and trying covert our older intelligent report to work with CDS 2.4. One of the criteria, which worked in the chemstation edition, is grouping and repeating on unknown impurities based on Compound_ExpectedRetTime, refer to image. On CDS 2.4 it does not group the peaks unless all the peaks are labeled, is there a way to do it without labeling all unknown peaks?
