Feature Request For "Sign in with"

It would be nice to be able to link unsupported providers.

For example, shopify isn't available but plenty of website use it. It would be nice to have a default "Provider not listed" option that would allow any record to be selected. That way we'd have a tracking for it. Currently I rely on adding notes to each site.

Bonus: Any records used as "sign in with" should keep appearing in the list even if the provider isn't supported.
