Allow translation data in another joint other then the root?

Hi,

I have a character that has a prop joint in his hand. The idea is I would parent a object such as a bat to the character's prop joint in Unity. I have some animation where the character throws the bat onto the ground. His prop joint has translation data in the animation. Problem is when I bring the animation into Unity, it seems to strip out the translation data in the prop joint. How do I get Unity it to play the animation in my prop joint? Does Unity strip out all translation data in a skeleton hierarchy other then the root joint?
