Exploiting symmetries while using Floquet boundary conditions

I have a periodic structure which utilizes Floquet BC's. The cubic unit cell has uniaxial 4-fold symmetry about the vertical y-axis. I am using a periodic port to launch a TM mode wave, polarized along the horizontal z-axis, and would like to utilize a PMC down the center of the unit cell (xy-plane) to cut the computational domain in half.
However, it is evident that by removing 1/2 of the computation domain I also remove the paired boundary for the Floquet BC. In other words, the PMC does not appropriately mirror the Floquet BC, since it does not track the phase advance.
Any thoughts on how--if at all--to exploit symmetries while still using Floquet BC's?
(Using v4.3b and the new Wave Optics module, but this problem applies to RF module just the same)
