Overwriting a parameter that is part of a view templat

Hi All,

i have created a Project Parameter for Views with the node “Parameter.CreateProjectParameter”. This works, but the Parameter is always part of the View Template, this is also clear, and the check mark is set in the box, that include the parameter on the view templatesettings. In the next step i want to override this parameter with “Element.SetParameterByName”. If the check mark is set this does not work.
Is there a way to solve this, or should I try to load a customized view template into the project via Dynamo?

Thanks for any tip
