Can you set up iPhone 5 to show all "outboxes" at once?

I'm new to the iPhone world. I noticed that you can view all inboxes at once. Is there a way to setup your phone so you can view all of your sent mail from your collective email accounts? Like a account labeled "outbox"?

I go WTF is "outboxes?" We say here SENTMAIL folder.
