Help creating a Throwing and catching animation on an item that is attached to a hand prefab

So I'm working on an app that lets you create mini animations, and play them back. Currently driving the people that we are animating through a mixamo rig. During playback, we can call different item prefabs, and attach them to a prefab thats attached to the hand. This works great with most items, but we are trying to implement some prefabs that will be thrown in the air and caught. We are wanting to attach these throwable items to the hand, then call a toss animation from the prefab, and then go back to being a static prefab that's attached to the hand again. I am lost on how to go about this. Any help would be greatly appreciated.
