Genesis Male to Genesis Female

JB007

Can somebody point me in the right direction please!

Where in the .duf files does it say the equivelant of "this is for Genesis 8 males" .. I have a hair product that's great but it would work perfecly well with Gen 8 females .. attaching it with Autofit works .. but obviously, you have to sit and wait while it does all the calculations and so I'd like to change what needs changing in the .duf files to make it automatically fit Gen 8 females ..

I know there's converters out there .. but I only want to do it for this one item .. 

Anybody know where I should be looking and what I should be looking for?

Thanks!
