Fader for fronts & rears possible ?

[BubbleBoy]

Im using WaterColour Ergonomic skin coz i like it, alterd the playlist a bit longer.
But the thing that catched my eye is that it shows in the equlizer my Bass and Treble "hardware sliders" from my philips 706, didnt know that was possible.
Is it also possible to ad a fade slider, to fade volume between the fronts and rears ?

At the moment no,there's just bass , treble ,and balance.Although it would be a good feature request.
