Camera rotation and position with ViveRig

I am implementing a Vive Rig in my Unity project. I have a specific view that I want all of my scenes to start with, but I need the flexibility to start at any location in the physical room I’m in. When the scene begins the camera initializes based on where in the physical location the user is. I want a simple method to rotate and translate the rig to compensate for this. Is there anything already out there that is available? Thanks!
