Ability to save on the "Email Bid Invitation" Screen (ITB)

It would be helpful to be able to save and ITB email in progress.

Once you select your vendors from the ITB page and click "Send Invitation", there is no way to save on the "Email Bid Invitation" screen. Just today, I was in the middle of sending one out (nearly finished), and I had to suddenly step away from my computer. By the time I got back to my computer a few hours later, my computer had signed out of Sage, and all my work was lost.
