Disable Agent transfer of calls on hold in queue

[kakashi]

Is there a way to disable the ability of an agent to transfer a call waiting in queue? All of our agents can right click any call waiting in their queue and manually transfer the call to another queue.

If the above cannot be done, is there any way to see who might be manually transferring a call by that method? We would like to stop this as soon as possible.
