S-parameter optimization problem

How can I perform an S-parameter optimization over a range of frequencies where the parameter is optimized at one frequency, then optimized again at another frequency, then optimized again at another frequency, and so on resulting in a list of optimum parameters for each frequency?

If I select a single point in SP1, then it results in the parameter optimized at that frequency. If I select a range of frequencies in SP1, then it results in the parameter optimized to best fit the frequency range but only produces one value whereas I want a separate optimized value at each frequency point.

I am attempting to determine the Z0 of a transmission line by optimizing the characteristic impedances of the Term component to give a minimum dB(S11). I have an S-parameter dataset of the transmission line measured over a range of frequencies and I want to calculate the Z0 of the transmission line at every frequency point so I can plot of graph of how the Z0 varies with frequency.
