Red Series 2-1 Switch - How to Switch Between Leading and Trailing Edge Dimming?

It was mentioned here that The Red Series 2-1 would be able to be configured to use trailing or leading edge dimming in some configurations. I have one setup in as a single-pole dimmer with neutral wire present, but I couldn’t find a z-wave parameter or button push combination to switch between the two dimming modes (I assume it’s in trailing edge based on that post). Does anyone know how to switch it to leading edge dimming? Or is this something that is coming in a future firmware update?
