How to make my game run in seated mode for VR

It’s great the there is now native support for OpenVR but I am making a seated experience so I want people who use the Vive to be able to play it in their seated position and to be able to use the InputTracking.Recenter command (“This only works with seated and standing experiences. Room scale experiences are not effected by Recenter.”).

But I can’t find anywhere that I can specify that it should be treated as a seated experience.

Just for some closure on this question because no one provided any solutions. I solved it by adding my own recenter script which just moves and rotates an object that contains the camera, so that the camera’s position is now at the point I want.
