Freezing Joing Transformations Help?!

im trying to zero out the transformations on my joints so when i bind the default position for all join transformation values is 0... but when i try to freeze transform tool, nothing happens, is there anyway to get around this?

Skeleton>Retargeting>Go to Neutral Pose
