"The View Template controller is a simple tool that enables you to visualize and change View Template assignments for views in your model. Just drag and drop views onto a View Template name and your views will update instantly taking on the new view template settings."
There's more information about this free add-in on the CASE Apps website.
Update 5/8/2016: CASE and the CASE Apps website are no more but, courtesy of WeWork, the CASE Apps are now open source. They may be accessed on GitHub.
