Loss tangent setting for user defined material


I am trying to define PEDOT: PSS in sim4life. I have both electric conductivity, permittivity, and loss tangent data of this material. But It seems that sim4life can only input electric conductivity value and relative permittivity, and then it will automatically give you the loss tangent. But the loss tangent given by the software has a large difference from the data I have. I wonder if this will influence the simulation results and if there is a way to edit loss tangent in sim4life?

the loss tangent from sim4life:

However, the loss tangent from the experiment is 0.58387.

Thank you,
