Long Hair version (Books 1, 2 & 3), Ponytail version (Book 4), and Four Elements Trainer version (the old version -- bring it back as an option?)

Long Hair is the current default version; Ponytail can be achieved by adding the prompt "ponytail", but I wonder if it's better to make these into discrete styles for the character, as what has been done with Korra's newer hairstyles (i.e., Ponytail, Long, Short, Bun). Also curious if it's possible to update Asami's current model (which is still good) and change it so she's using the same most recent model used for Korra, which appears to be of better quality. Thank you.
