Ability to select a separate Post for each Form's email verification link

Under the email verification settings, I'd like to be able to specify which post is linked to in the {verificationlink} field. That way we can have each form return the user to a different verification page. 

Also, it would be useful to be able to have the {verificationlink] embedded in a <a> tag so the email is a little cleaner. I'm not sure if this is a problem with my SMTP plugin, but I get errors when I try to add the {verificationlink} as the link in the email editor.
