Welcome to the forum @Roy.guevara.78!

Sadly, the official forum language is English (annars skulle jag bara posta på svenska så att jag kunde öva). This is a technical requirement to make search work. Please translate future posts to English, optionally keeping your native language post separated by a line or other demarcation as I did in the edit of your post.

Thanks!

Unfortunately, there is no way to create project parameters via the API in Revit, which means you cannot directly automate it with a Dynamo node, scripting, or C# code.

Instead, I recommend you create a shared parameter which should be more readily doable.
