@SaintFox, The dials would still be there, only hidden.  You could just apply a simple pose, eg:

{

version
        {
        number 4.01
        }
actor head
        {
        channels
                {
                targetGeom SmileLeft
                        {
                        hidden 0
                        }
                targetGeom SmileRight
                        {
                        hidden 0
                        }
                }
        }
}
