You can do a third level with the format <sub>.<team-name>.vercel.app. Otherwise, you can use your own custom domain for more flexibility with subdomains.
right, but i’d have to add these manually, right? i was looking for something that automatically creates them, like vercel preview urls—without having to set up complex github actions myself.
Just some other information, If you are looking to specifically handle preview deployment urls, you can use this documentation (pro and enterprise accounts only) to bring your own domain instead of using the vercel.app suffix.
