QTR-Quadtone RIP

I have an Epson R1800.  I just purchased the inks necessary for 3MK 
printing.  I'm looking forward to better black and white.  While I'm 
at it though, I'd like to be able to tone those prints using the 
existing color inks.
I see that selecting the normal QuadR1800 printer settings gives me 
curves for black, cool, and sepia.  Selecting the QuadR1800-3MK 
settings gives me many paper options, but no black/cool/sepia options 
under those papers.
I understand using color pigments undermines part of the purpose of 
the 3MK system, but I'd still like to try it.
How do I go about getting toned curves for use with the 3MK system?  
If the answer is to develop my own curves, I guess I'm out of luck.  I 
don't hold out much hope that I'd be able to manage that.
So, do such curves exist, or is there some easy way of dialing in a 
little red while I'm printing with the 3MK and just winging it?
