Parameter.CreateProjectParameter - How to modify discipline of Project Parameter?

Hello , I am a new in dynamo.And I am trying to use Parameter.CreateProjectParameter node to create parameter by batch. But i find out that the Discipline is “Common” by default. Is there any way to modify Discipline? Thanks a lot!!
I also have column for discipline, but seems like there is no input slot for modification.


From the Revit client. I’m fairly sure the discipline cannot be modified, the breakdown between different Disciplines is intentional and can’t be added to/deleted.

Thanks for your reply! It is because all parameters created by this node is default in “Common” Discipline which i wish it will be “HVAC”, so that my target is to change the Discipline from “Common” to “HVAC” through this node.Is it also impossible ?
