Adding a list of complex permittivity and permeability values vs frequency

I am attempting to add a Ferrite material to my EMPro simulation. I have data from the Ferrite manufacturer of the material properties in complex permittivity and complex permeability vs frequency. I would like to add the data via the Python API and I haven't found a class which would allow me to add multiple complex permittivity and permeability values vs frequency to a material.
