Create schedule with shared parameters

Hi everyone.
Does anybody know how to create a schedule with shared parameters (other than the default ‘SchedulableFields’)?
Even if it has to be through the API (I’m a Python beginner)
Thanks!!

Assuming the shared parameter is already within the model file:

@Robert_Younger, You are right. The problem was that the parameter is not in the same order in the list inside Dynamo as it shows in the Revit Schedule Properties, so I did’nt realize that it was already there!
Thank You!
