I don't think there is, unless maybe you have a registered copy of FSUIPC and if CS has made it possible to manipulate through FSUIPC.

I find it impossible to use the pitch/roll knob in the VC, as any pitch command invariably gets interpreted as a desire to roll.

I have the 2D pop-up AP panel on my 2nd monitor at all times for handy use, or you can use the buttonbar panel or press Shift-4 to access it.

So long as you click above center or below center on the 2D panel, it always interprets it as a pitch change and never a roll change.

Hope it helps. 8-)
