Timed event/peak pattern calibration in Open lab

[dadzi]

Hi everyone, hope someone can help. I'm doing a kerosene analysis using Open Lab, I cannot figure out how to identify the compound as a timed group -- so the area of all peaks from 4-13 minutes are collectively identified and calibrated, with a curve shown for this compound. The only thing I've found is how to set up a peak summing table. Googling the topic takes me to the online manuals, which only state what can be done, it really doesn't walk you through how to do this. The only thing I've seen that may work is to create a compound group and add in the individual peaks during that time frame, but that's a) tedious, and b) seems to leave out some peaks while including others.
[My lab is (eventually) switching from TotalChrom to Open Lab, b/c TotalChrom won't run our 7890 GCs. It's amazing that it takes mere seconds to do this in TotalChrom, but I've spent hours trying to figure it out for Open Lab, with no success]

Running 7890 is not only OpenLab capability.
But integrating a zone of chromatogram is a challenging task to make it in human-oriented way.

AFAIK in ChemStation/OpenLab - you have to manually integrate (i.e. insert peak as manual integration event
from t1 to t2 - i.e. manually enter t1-start and t2-end integration)
then specify the name of a peak in calibration table with appropriate time frame for proper identification.

Our product UniChrom can do this in such manner.
1. Enable macro recording (single click)
2. Place left maker at the beginning of region (single click)
3. Place right marker at the end of the region (single click)
4. Press [Ctrl]+[+] or toolbar [+ Peak] (single click)
