Simulating impedance of frequency dependent load in Tina Ti

Hello!

I have data gathered about a specific load I am testing with and its transform function in the s-domain. The impedance is frequency dependent, and I would like to simulate that in Tina TI. I am unsure of the syntax or possibility of being able to do this. I have shown a way to handle this in LTspice, and hoping I could replicate that in Tina TI. Note, there might a simpler way to do it in Tina TI, and I am hoping that someone could point me in the right direction.

I set up a voltage controlled current source, that is dependent upon the voltage across the load. The load is a current source defined as a 5th order laplace transform. The a and b coefficients are defined in a parameter list called parameters.sp, and I can manipulate there values using a step param function that goes through different if statements inside the parameter spice file. This is just the way I did it, I hope there are potentially easier ways to accomplish this. I appreciate any help. Thank you!
