> Hi there, I have created a Shared Parameter. Now, I would like to add this Shared Parameter as a Project Parameters, define its Group Parameter (SET) as well as its Category (Sheets). This was the simplified version of the routine I need to solve, which is: I have created MANY shared parameters and now I need to add them one by one to the template and that will take a tedious amount of time! This way I am hoping to do it by Dynamo!! Thanks!

I think you can all categories as a list…!

f.e.

```auto
import clr

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager

# Import RevitAPI
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument

OUT = [i.Name for i in doc.Settings.Categories]

```
