Custom Concrete material [SOLVED]

My question is regarding grasshopper component ‘CustomMaterial’. I want to create a custom concrete class with same strength as C45/55 but a modified density to match a specific geometry. However in the CustomMaterial component I do not get to insert the compressive strengths. I notice that a custom material created with this component appears under the category ‘General’ in the FEM model created with the script. Could you help me to create this custom concrete class right?
