Targeted Color Balancing

Using an X-Rite (Or Golden Thread) color balance card while doing copywork. Is there a method of using Advanced Color Editor to adjust colors to specific values, hopefully using a dropper. I need to match the RGB values to the card. I only color balance numerically, not by eye. For instance, I need to make the red square on the card R175 G54 and B60, so how can I force it to those values?
I can white balance fine. Want to define RGB values specifically per channel.
Any input would be greatly appreciated.

Shooting with H2s and some Schneider-Kreuznach lenses, Phase One DBs P45+ and P65+.

Thanks,
CL

  I saw below Alex's post regarding matching RGB values to a color balance card such as X-Rite or Gretagmacbeth (same company now?), and I share his disappointment in not being able to match color values to a card in C1. Basically this means I have to process the entire image with the card included, then use Photoshop to color balance. Which basically makes C1 only good for capture and RAW processing in a studio. And I'd rather color balance the RAW image before I output it to TIFF.
  
  Color balancing by eye, even if you've used a spider or something like Eye-One Match to color balance your monitor, is wonky, and you're only going to get truly "correct" colors if you work with numeric values.
  
  I wonder if I can find a workaround by using the "skin tone" thingy.
  
  I really like C1 and have been using it for several years now. For capture during a session it is way beyond anything else I've tried. But this color balance issue if a problem. If I'm missing something here someone please let me know.
  
  Thanks,
