Send message in Outlook and move it to “waiting” folder

I am looking for a way to make outlook send the message I'm currently editing and put it in a "Waiting" folder (and not the Sent messages). 

If such a sequence is not possible, I thought of adding the text *WF* at the bottom, adding myself as bcc and save and then have a separate rule that moves any message with *WF* to the waiting folder.
