HFSS - Materials Properties in Fields Calculator

The parameter I'm interested in calculating is dependent on the material properties of one block. Unfortunately, I can't just plug in the numbers, as this material is very frequency-dependent in the range I'm interested in.

Is there a way to extract frequency-dependent material properties in a volume into the field calculator? Like is there a way to extract the tanσ and ε', or ε' and ε", or even n and k from a volume?

I'm sort of new to antennas and thinking about problems in this way, would one of the other built in calculated parameters include this information?

Thanks in advance.
