[Plugin: Contact Form 7] Move error and thank you messages to the top

We’ve got very long forms on this website, and the “thank you” and error messages appear on the botto of the page where the user can’t see them without scrolling after they submit the form. I was digging through the source code, but I don’t see where I can move those error messages from the bottom of the form up to the top. Can anyone point me to the right file?
