This is a similar thing to what I'm thinking as well. I don't believe they have the ability just yet. I am thinking this would be a situation where if you are the presenter (since you should have the ability to pass the baton), you see the presenter slide and screen if chosen as an option (selectable by the more options button in the control bar). This would show you the slide notes, current slide, next slide, clock & timer, and provide tools to draw on the slide using marker style highlighting.
