Network S-Parameters in Simulink

Using the example: "Lossy Multiconductor Transmission Line Circuit", how do I extract the full network sparameters within the Simulink model (simrf_coupled_pb) from Vin to Vout as is done in the matlab code line:

setports(ckt,[1 0],[15 0])

S_vout = sparameters(ckt,freqfit)

I'd like to find a way to do this all in simulink if possible to avoid building circuits in matlab, and instead simply build a network in simulink, pick two ports and measure the s-parameters. Thank you so much.
