RFmodule: Exploiting Symmetries AND use of Periodic B.Conditions

In RFmodule, 3D harmonic propagation analysis:
Let's say I have a 2D periodic strucure, e.g. a 2D-grating (in the xy-plane) .
Incoming light is a plane wave, polarisation: x-direction , travelling along z-direction, i.e. normal incidence onto the structure (no in-plane k-vektor component).
As boundary condition I'd set periodic conditions in x-, and in y-direction.
Now, in case my elementary cell exhibits symmetries, e.g. elementary cell just consists of a centered cube, I'd like to introduce a perfect-magnetic conductor (xz)plane and a perfect-electric conductor (yz)plane mirroring those symmetries.
To take advantage of those symmetries I have to deactivate the corresponding subdomains.
But then I experience, that I cannot use the periodic conditions anymore, since parts of the periodic-condition boundary-pairs now lie on deactivated subdomains!
Anyone knows how to implement that kind of problem? Or is it just, one cannot exploit symmetries when using periodic boundary conditions?
Regards & thanks in advance

I am having exactly the same problem as you. I was wondering if you were able find a solution meanwhile. Thanks!
