Stop the tree list from scrolling?

Can we have a modifier key or some other means to stop the tree list in the left inspector from scrolling when something is selected in the canvas? When I hook up widgets or cells with actions, I often have to drag the rubberband across the canvas to the tree list to hook up a cell or widget. Now, whenever I select something in the canvas, the tree scrolls to that position to bring the object that I have highlighted into view. It costs me so much time to scroll back to the section with the cells I want to hook up. Can you make this optional or a pref or suspend this behaviour by way of pressing a modifier key?
