Hi William it’s not possible at present. But bear in mind this is an early release of Lightroom for Apple TV. I’m sure Adobe will be bringing forward the kind of features you are looking for in future iterations but for now the actions available via your remote control are limited. Have a look at Scott Kelby’s tongue in cheek FAQ where all the answers are no, including your question. Of course you can view in date or custom order on the iPad or iPhone until the TV version catches up.
