How to create custom reference data for ColorChecker Charts using X-Rite ColorChecker Camera Calibration?

I am using ColorChecker Camera Calibration v2.0 in combination with Colorchecker Digital SG achieving the most colourimetric accurate colours. At the moment the software is using the values given by the ColorChecker manufacturer (X-Rite). But I have profiled all the patches of the target using a colourimeter and I would like to use those values instead. I can’t find a way to do that searching on the internet. Is there any way I can access and modify the reference values of the targets?

If you are not used to scientific photography please read the description of why I need this at the following link (archived copy). My question is simply: how can I do that with ColorChecker Camera Calibration software instead of i1Profiler as I do now.
