Panel Merge a330/a340 CLS-Posky

Hi,Has anyone found a way to merge these panels (i.e. use the CLS a330/a340 panels with the Posky a/c)?The problem I have is that oddly in the 2D overhead panel (with CLS and Posky) I get either the Fuel panel or the Electrics panel, not both. If the flight starts (I begin 'cold & dark') with no Electrics switches on the 2D overhead panel, I can't start the batteries etc.! In the CLS a/c, I can go over to the VC cockpit, where the full overhead panel (with both fuel and electrics) always shows, and turn on the switches there. In a Posky a/c with the CLS panel, the switches in the VC are all non-functioning. So I can't start the elctrics.Any ideas? Thanks..Martin
