Could I use one nodeTemplate for all different node types?

GoJS
1 
In one diagram, except the 6 normal nodes, there should be 2 zones and 2 annotations of the zones.  I have already  created 6 nodes by one myDiagram.nodeTemplate, but I'm confused  that how to create the 2 zones and their annotations?  to make another template and use nodeTemplateMap? 
Thanks

Use Groups for your zones.
