Removing submission pop up messages in Pro version 9

Hi,
 
Could anyone advise me if there is a way to remove all of the automatic form submission messages that tell the end user what to do with the pdf form after completion. e.g outgoing message notification and select email client and associated blurb when sending a pdf form manually.
 
Whilst these messages are helpful to the majority of users, I have been told that they may be too confusing for some of our users and would just like them to hit submit and for the form to be sent. Our mailbox is then set-up to send a thank you reply.
 
Any guidance appreciated.
 
Many thanks
 
Alan
