Prevent date changes in scheduler when dragging

Is it possible to prevent events from being moved in the X axis when dragging them around on the Scheduler? Our use case is assigned jobs from one user (resource) to another, however the dates must remain fixed to their original values.

I know I can do this server-side in EventMove by just reassigning the OldStart/OldEnd values, but it would be more intuitive for the user if they were restricted as they were dragging.
