Can I add passive components in CST?

Can I add passive components in CST? I have built a Wilkinson Power Divider with its connectors and so on, but I don't know how to add the resistor connecting both arms. Please help me!

yes of course you can, go to solve\lumped elements and then define the parameters you need. This is the case in version 5 and I think it was the same in version 4 too
