Cadence EMX: Top Shield Definition in .proc File

Hello,

Does anyone know if we can add a top shield (a non-GDS layer, a top PEC across the whole chip by default) to the process file in EMX?

Or equivalently, is there a way to modify "layer infinity 1" (top infinite air) to represent a top (perfect) metal rather than air?

I am able to add dielectric layers at the top below the infinite air, but I don't know the syntax for a top PEC (without defining a new GDS layer or a dielectric layer with a very high conductivity...

In all cases, if the tool is capable of handling such a thing...)

Thanks.
