Question How to use an instantiated target transform in TwoBoneIk Animation Rigging?

So, Animation Rigging is really cool and there are all these great videos showing us how you can use it with an existing attached game object such as a weapon, but I cannot find any information on how to use an instantiated object as a target. I can't imagine there are too many successful games that would only allow a player to have a single object that's always available, so there must be some trick to this. So.... how do you set the IK target of a rig if your object doesn't exist until after runtime?

I've tried the following

Code (CSharp):

1. RightHandIk.data.target = rod.RodIKPoint.transform;
2. LeftHandIk.data.target = rod.ReelIKPoint.transform;
