This is big issue I'm facing with multiple users. They are trying to redirect a custom page, but can't because this message pops up.

For instance, they want yourdomain.com/freechallengesignup to redirect to yourdomain.com/waitlist. They can't set this up, though, because the domain & path combo is already in use. Which is true because they are already using it for a page. But that shouldn't affect the redirect. They need that page to be redirected to the other one.

They also can't set up a redirect on the entire domain because they are using it elsewhere for other pages. So, setting the path as /* would not work in this case
