Single Sign On specifiyng authentication provider in Creatio URL

Hello

If multiple authentication providers are set in single-sign-on configuration, users must select their one in the login page (there's a link for each authentication provider below the "LOGIN BUTTON"):

Usually a Creatio user doesn't even know what an authentication provider is and he doesn't know what to click in login page.

How can Creatio be accessed specifiyng in the URL what authentication provider should be used?

Thanks
