How can I change the CameraOffset of the Humanoid?

If you make a Custom Character, it needs to have a Humanoid. If you click on Humanoid, you can access the Properties where you can see a CameraOffset option. But if you change that and then try out your game the CameraOffset will change back to its defaults (0,0,0). You can see this by clicking on the Model with your name in Workspace and then clicking Humanoid. How can I change the CameraOffset?
