MRTK ObjectManipulator is there a way to change the rotation speed / Force

That question may seem dumb, and I cant even provide code. Iam currently working with the MRTK Toolkit and created a rotateable Knob. Ive implemented a to the z axis restricted rotation with the ObjectManipulator provided by the MRTK Toolkit. So far its a really great tool, but when rotateing the knob I noticed that it is really difficult to get a full rotation with my hand without repositioning. So my goal is to increase the rotation of the object in comparison to the rotation of my hand.

Anyone worked with this tool and can provide some tipps? Are there some hidden parameters I can use or do I need to implement the rotation from scratch in that case.

Best regards
