Compound Group Amount / Curve reference

I am working on the project team for my site's transition from OpenLAB Chemstation CDS C.01.07 to OpenLAB CDS 2.5 and while working in our development system I have found that I can not use a group compound as the curve reference for other peaks.  In our old/current system (C.01.07) I could use a group compound amount in the calibration and reference one of the compounds in the group for un-calibrated peaks (see below pictures).  Is there any way to do this in OpenLAB CDS 2.5?
