QTR-Quadtone RIP

This should be an easy one. I am now using a paper with my E2200 printer for which no curve exists on my QTR. I am using Moab Lasal paper, but since no curve exists for it I am forced to use either the curve for Epson Enhanced Matte or Moab Entrata. There are probably OK, but I may be able to get a better print if I have the Lasal/E2200 curve. Moab has it available for downloading; I did that and am using it when I print in color from Photoshop CS4 -- but how do I get it to show up in my curves choices for QTR?

Thanks for any help that may be forthcoming.
