I am a writer whose characters are ethnic. The AI defaults to describing all of my characters as caucasian. I would like to be able to create character profiles so that when I'm selecting "re-write" or selecting "auto" or "guided" or something that the platform can use the descriptions I've indicated for my characters. It sucks having to go in and use my wordcount to fix character descriptions. **also** can we allow rewrite's custom feature to allow more text?
