How to use Impedance Measuring (Frequency Scan) Block to measure the Mutual Impedance between two ports in three-phases system?

Hi, I need to measure the impedance responses over different frequencies between two buses in a three phases system. I know the Impedance Measurement Block is capable of doing that, but is it ideal for only one port in a simple circuit? Images of both cases are attached. The impedance measurement block can accurately find the self-impedance at port 1 (Z11) or port 2 (Z22), but not the mutual impedance(Z12). The result is incorrect if simply connect the block between two ports. I would like to know: 1. how should the Impedance measurement block be connected in the simple circuit in order to find the mutual impedance? 2. how should the impedance measurement block be implemented in a three phase system? Any feedback is appreciated. Thanks.

Based on the information shred in the link: Impedance Measurement are you taking care of the Multiplication factor for Line to Line impedance measurement.
