Specific notification for unregistered email addresses

I have customers who think they have a registered community account when they do not.

When they enter their email that is not currently associated with a community account, is there any way the platform can check if the entered email address is unregistered and, if so, display a more specific message informing them that the email entered is not a registered email and prompt them to ‘Create an Account’, rather than showing this generic error message?
