At least not until the point of confirming an order. 
As the example I used yesterday wouldn't let me confirm the order, then I'm not sure where the option would be to book a return.

Understand there's some glitches with the app as launched - they somewhat appear to have been amended today (although Billingham isn't showing as a destination despite the Railway Station supposedly being one (not the Town Centre oddly).
The app wouldn't allow for booking yesterday as it hadn't launched yet - you can book now but the journey you were attempting to book won't be possibly anyway as Saltburn isn't available to be a destination.
