As shown below there is a drop down for different Face options.  I'm trying to add additional textures to the drop down here.  Some models have it, but i can't seem to make rhyme or reason of how it's accomplished.  I want to include different makeup options with each model.  @anyone know how to achieve this?  What do i have to do, name the files a special way, a different folder in the look?  Please help 
  Thanks!
