I have a lot of page that shares most of windows in common, such as NavWindow, FooterWindow, etc., only different is the portlet in the ContentWindow. Can I let them share some page template, so I don't need to do a lot of copy-paste in the xxx-objects.xml?
we don't implement that in the model for now.
we thought about shoving it in 2.2 but that was out of the scope of the roadmap and would have taken lot of time to implement it properly.
there are many side effects that needs to be discussed like security.
