Not at all. As you can see from other discussions on this list there are

Maybe there is a better solution, but using 'no_message.pt' as default
and hard-coding additional templates in the view class should work for you:
def __call__(self):
if self.isTuesday():
return ZopeTwoPageTemplateFile('tuesday.pt').__of__(self)()
return self.index()
