I currently am creating custom shapes on the fly that are being placed onto my NDrawingDocument. My shapes are similar to the following:

public class MyShape : NGroup
{
public MyShape()
{
//Put some shapes into the group
}
}

I can programmatically add these to the document and then manipulate them using the Pointer tool, etc. without any issues. My problem is I need to place them on a toolbar so that a user can draw a brand new one on the Document. How do I go about doing that? Any code examples would be great.
