Generate Zth transient thermal impedance curves with Simscape

Simscape has some nice thermal domain elements like Cauer thermal model elements.
I was looking to generate a set of Zth curves using a set of known Cauer models. I am thinking of the transient thermal impedance curves such as shown in Figure 2 of https://assets.nexperia.com/documents/application-note/AN11156.pdf
I can think of how to do this manually. You input a pulse and measure the power of the pulse, and you look at the temp rise associated with that pulse. dT/dP gives you the point for that pulse duration. I think for pulse trains / duty cycle you do the same thing, but you wait for temp equilibrium to establish dT/dP.
What I'm not sure how to do with Simscape is run a plot that automatically sweeps all of the above.
There's a nice example of what one can do in native Matlab here: https://www.mathworks.com/matlabcentral/fileexchange/48026-evolutionary-curve-fitting?s_tid=srchtitle_thermal%2520impedance_3
but I'm not sure how one would extend it to Simscape / graphical interface.

Simscape Electrical provides some good examples about how to optimize parameters and generate characteristics that I believe are relevant in this case. Below is a list of selected examples:
