XDJ-RX3 Touch Screen and unable to scroll up and down in tracks

Can anyone advise from Pioneer DJ if there are any plans to allow a finger touch on the XDJ-RX3 to scroll up and down through tracks?

At present you have to use the dial on the right side to scroll up and down, but as it's a touch screen, surely we should be able to scroll up and down with a finger touch gesture? 

Can a software update fix this or is this yet another limitation of the screen / processor?
