How do I make a character face the last direction it moved?

So I made all of the sprites for my character. It's important to note that its "running left" and "standing left" sprites are different from its right counterparts because he is asymmetrical so I didn't simply use the "Mirrored" event when running to the left.

I've already set up the running right and left animations and left and right standing animations but when I stop running to the left it goes right back to his "Standing Right" sprite. How can I make it so he faces to the left when he stops running to the left?
