Heterochromia! That is one heck of a great idea!

Very specific but I would like an option to copy an alien sim's facial features onto his human disguise... It's available for vampires and I don't understand why it's not a thing on aliens? I like them to have a human form that is as close as possible to their alien face, I think it's more realistic that way (and also I don't want to have to spend an hour making two sims instead of only one thank you)
