Nice, that was quick. I already tested this out on a couple images, really liking it so far and definitely going to be using this on my pack.
Including sorting the race list alphabetically you mentioned here's some other suggestions you might want to add if it isn't too difficult, to make things more convenient.
I think some attributes should be grayed out based on selected race since they won't appear with those attributes in Strive. So you don't have to look through scripts, Kazama already posted a sheet here in what hair colour and skin-tone each race supports. https://itch.io/post/508815
That entire upper right image selection box will be better if moved to the left or right of attributes selection. For bigger selection to select portraits from and won't have to scroll much.
Maybe a way to select attributes for multiple images through shift clicking or something?
