Custom domains for URL slugs

As great as Base44 is at building CMS systems, being limited to URL slugs for customer landing pages is a showstopper disadvantage. Customers expect custom domain support since all of the big players offer this. I realize it would require some finessing on the DNS side and can be fairly complex, but it is entirely doable. I have done in Node via NGINX reverse proxy scripting. Please consider. It would be a huge vale add.
