SOLVED-Layered image preset in Poser 9?

I've been experimenting with the Layered Image Editor (LIE) in DS 4.8.  It's very useful for adding a dirt/grunge layer on top of existing textures.  Now that it comes to converting to poser, however, I don't know if the same thing exists.  On googling, it looks like it is available in Poser 11, but I only have P9.  Is anything like that available?  I'm already fearing the answer is no, so is there a workaround?  Or do I just have to make a unique texture and MAT file for every texture with the dirt layer included?
