I would like to combine the features from the scrollbar version and the range version of the JQueryUI slider.

http://jqueryui.com/slider/#range

http://jqueryui.com/slider/#side-scroll

So can I create a range slider (so it has two handles that adjust the range) but add a click handler to the space in between the handles that causes a dragging action? I'd like clicking and dragging the space between the handles to move both handles relative to the dragging. Currently, clicking between the handles causes one of the handles to change values to the click point.
