sorry i didn't quite understood you ; but here what i personally do
basically i put all the latina ( or other "race" of model) into a temporary file ;
after that i sorted them out by color of hair and by actress (since in my mod i do 2 or 3 portrait for one actress, so if i want to have all the brunette first, i take all the brunette and rename them 1.png,2.png ... until all are renamed
after this i do the same for blonde and thus if for example i have 25 portrait of brunette model, and that (let say) my first blonde model portrait is for bridgette b, well the first portrait of her will be name 26.png
this way allow me to know that the brunette( or dark hair) are first , the blonde are second and the redhead are 3rd and if i have some portrait of girl who dye he hair on a unusual color (like purple or other ) i put them in last
this process allow to find the portrait i want quicker and more efficiently
