How can I export transfer functions or data from System Identification app to MATLAB workspace using a script?

I am working with System Identification Toolbox, and have found the method to call on my SID file to load all data from the SID, but am not able to find any information on exporting that data or the transfer functions in System Identification app to the MATLAB workspace via commands in my script rather than having to manually re-enter them into my workspace via the GUI. How can I export the transfer functions or data from the app to the workspace programmatically?

.sid file? How did you read it? https://www.mathworks.com/matlabcentral/answers/67730-how-can-i-open-multi-spctral-image-file-sid-in-matlab#answer_79162

From: https://www.mathworks.com/help/ident/ref/systemidentification-app.html?searchHighlight=systemidentification&s_tid=doc_srchtitle - systemIdentification('mySession') opens the app and loads the previously saved app session mySession.sid

Suppose you have a SID file named "testit.sid", use the following command to generate a struct named "S".

S = load('testit.sid', '-mat');

"S" will now contain several fields. The field named "Data" will be a cell array of "iddata", with one entry for each square that is filled in in the "Import data" section. The field named "Model" will be a cell array of various data types, with one entry for each square that is filled in in the "Import models" section.
