Tween posistion to a moving endpoint

Iv been having difficulty fining a way to update a tween path while its in use. Im using Prime[31]'s GoKit.

I have a coin GameObject that when collected needs to move to another GameObject witch is a child of the camera. Once at the end point the coin object is destroyed. As the camera moves around the end point of the tween path will have changed. Is there a way to update where the position of the last end point should be?

Any ideas that dont involve a tween would be equivalently helpful.

You can use the Update functions in iTween, like MoveUpdate which is a function/method that can be used in Unity/MonoBehavior’s Update function/method. If you have a reference or script on the game object you can modify the values during the updates calls.

iTween Documentation.

Iv read over what little documentation I could find for GoKit here, and was unable to find any similar methods I could use.
