How can I use different inputs for each "parameter estimation" experiment?

I would like to figure out a way to use different input timeseries to my Simulink model for each experiment of a Parameter Estimation effort. In other words, I would like to have multiple experiments, each experiment having it's own set of 2 or 3 timeseries inputs (Torque, Temperature, Voltage, etc.). The overall effort will still try to find a single parameter set that meets the overall set of experiments.
I can understand how to do this with a single variable - because I could define each experiment to tune a variable that I actually force to a value that I want for that experiment (for example, I tell it a "current limit" of 1.7, that can vary between 1.6999 and 1.7001 for Experiment 1, and I can set this to something differnt for Experiement 2... like 2.0, varying between 1.9999 and 2.0001). But I am not sure of a way to do something similar for using different input timeseries for each Experiment.
Please let me know if you have a workaround or way to do this that I am missing.

I now see that I can use an InPort and that the "input" section will show up when designing my experiments - so I think this answers my issue. It was there in the documentation.

Hi,
The time series as an input signal for your simulink model can be achieved via input source blocks, i.e. [From Workspace], [Constant], [From File], [From Spreadsheet], etc.
Good luck

Yes, I do have time series as an input signal now. But I would like each "experiment" in my parameter estimation effort to utilize it's own unique set of input and output time series. I'm wondering how I can vary these from experiment to experiment.
