Is there a way to edit post URLs before they're published?

I’d like to be able to set custom links for posts before I publish them. I know I can change the slug after publishing or work around it by setting a slug-like Title pre-publish and then changing the Title post-publish but that’s additional work every time.

More importantly, changing the link or title after publishing will interfere with all the places I’ve set to autoshare new blog entires via its RSS feed. For example, it could result in wrong links or titles on Twitter and Mastodon.
