QTR-Quadtone RIP

Is this possible?

 when working in the "curve creation" mode, if you select "load 
curve" as opposed to "gray ink" or "toner" you get a curve tab where 
you would normally enter the ink density.
 from that point, you can open up the "curve points/point list". it 
appears the only way to get information there is to enter it manually.
 is it possible to load or display the information (points) from a 
curve that has been created with the "toner/density/limit" method.
 
 in other words, if I where to open up a UCpk-raw-neut curve (on a 
3800), could I display the curve in the point list that was created 
for the light magenta channel when it was selected as a toner 2 with 
a density @ 25 and limit @ 6 originally?

 I hope to take that toner curve, and make very small adjustments to 
it, but I want to use the current curve as my starting point as 
opposed to creating one totally from scratch.

any help would be greatly appreciated.
