Dawn 11 - Different Banner Images for Mobile & Desktop?

My banner image currently (being a widescreen image) is a little off putting for the mobile layout, at least in my opinion. I want to use a 9:16 image for mobile users but I’m not sure if this is even possible on Dawn. So if a person loads into my store on their pc, they will see one image on the Image Banner, but a different one if loaded in via mobile.
