Enforce URL rules when posting content types so I created a content type "Regions" - This includes the 13 provinces in Canada listed as individual terms.

When creating a new post with the content type "Regions", you have to choose which term to post into. Let's say I would like to post a page "TEST POST ONTARIO", I post it in the term "Ontario"

I would like the URL from this post to be automatically changed to
www.website.com/region/on/testpost
by default, it posts to www.website.com/testpost

Is there a way to automate the url for when this content type is created? or would you have to manually change the url alias every post?
You want to use the PathAuto module.  This lets you create default patterns on a per content type basis that can use information from fields on the node to create a URL.
