For P5 and up, you can also make a generic pose file that will force limits on the selected actor, by using "actor $CURRENT", eg: {

version
        {
        number 5
        }

actor $CURRENT
        {
        channels
                {
                targetGeom PBMCC_04
                        {
                        forceLimits 1
                        min -0
                        max 1
                        }
                rotateX xrot
                        {
                        forceLimits 1
                        }
                rotateY yrot
                        {
                        forceLimits 1
                        }
                rotateZ zrot
                        {
                        forceLimits 1
                        }
                }
        }
}
