Adding Several layers of folders that contain .XSD Schemas to a .NET 2005 setup project

Question

I need to add .xsd schemas to deploy on a target machine in my .NET 2005 setup project. I've added individual schemas in the past with no problem. In this scenario, I have four folders that each contain several sub-folders and schemas at every level. Is there an easy way to add this in "one shot"? If not, the alternative is to create every folder and sub-folder, then individually add the schema(s) at every level.
