Remove name prefix in Sandcastle

Question

I have a big project with long namespaces like

CompanyName.Product.Component.Class 

Using Sandcastle to create documentation for namespaces, but those long namespaces really messed up the display of the content area in the last chm file. How can I only display Component.Class , at least in the Treeview panel?

And / Or maybe CompanyName as the root of the node, which extends to Product , which then extends to Component , expanding to all namespaces in the Component section?
