Rematch Button in unranked games?

Where is the rematch button? My friend and I agreed that this was the best option when we were playing the demo locally. We'd beat each other up, and be down for a rematch right away.

Now we purchased this game during the sale on the PS4. There is no rematch button when we play, and it is a total buzz kill. Just when my friend hits my with an unfair superman punch and knocks me out, I can't wait to play the next game. But what do we have to do to play another. Quit, loading screen, open new game, loading, invite, loading, wait for player, choose player, loading, watch intro, then finally fight. It takes forever, and not being able to rematch quickly ocmpletely ruins the game for us. Please add one!
