Add layer to a compound wall

Hello all,
I’m new with Dynamo. I have to create a wall with its layers. So I thought to start duplicating a general wall and replacing the material layers and widths with the Clockwork’s “FamilyType.SetCompoundLayerWidth” and “FamilyType.SetCompoundLayerMaterial”. The problem now is that I have to add new layers but I don’t know how.
I have read some discussions about this topic but I have not found an exhaustive answer.
Thank you for the courtesy

I don’t think it is possible. In this case I would probably simply replace the wall type with one that has more layers…
