Floquet type periodic boundary conditions in piezoelectric module

I am now trying to calculate acoustic waves in a periodic structure, so I need to apply Floquet type periodic boundary conditions.
I added the predefined piezoelectric devices module and it shows 2 modules (solid and electrostatics) and a multiphysics node coupling them.
The problem is, I can apply Floquet type periodic conditions (of u) in solid module but cannot apply them (of V) in the electrostatics module. There is no Floquet option.
As I remember in previous versions (such as 4.3) the piezoelectric devices module is a single physics including the both, and I could set the Floquet conditions for both u and V in one node.
So how can I do this in version 5.1?
I know that maybe I could use pointwise or weak constraints to achieve that, but it becomes more complicated than previous versions, which is unreasonable...
Or is there another way?
Thanks!
