specify masterpage of subdirectory pages in web.config

I know its possible to specify the masterpage of all pages using the pages element of the web.config but is it possible to specify that for all the pages under /foo/ that they should have a certain master page, and specify this in the root web.config.

I know this can probably be achieve开发者_开发技巧d by putting another web.config in the subdirectories that I want that specific masterpage to override but if possible I'd like to keep all of it in the one spot as when we change one section master page we are most likely going to be changing a few of them.
