If they're an Escort dealer then they should have the requisite fabrication skills to accommodate you.
I've done the same thing that you want with an E46 M3 I had and the V1 and Lidatek LE-30 (laser jammer) remote displays. I used a piece of wood panel I got at a hobby store (and painted black). Cut to the right size it fits right on the lip of the ashtray. Then just make the holes for the displays. I had to poke out a hole in the back of the ashtray for the wires to come through. It really wasn't hard and I assume not much harder with the E92. You could very likely do it yourself. But Murray Motors should be able to do this for you with with no problems.
