So I got the pathauto module up and running. I enabled my path module from the core and also got the token module the video tutorial spoke about. When I create new content, such as a blog post, the URL is nice and neat just as the tutorial indicates it will be. It's a nice feature to have. But now my only issue is making it so that my previously created content can also have their URLs automatically applied via pathauto. As of now I'm still seeing "node/4" type paths for my existing content.

Would I have to go into each piece of content and manually change the URL settings so that the "Automatic alias" box is ticked? I was kind of hoping there was a shortcut around doing this for everything I've created so far on my site. I just want to make sure all my URL paths are nice and neat for the finished text site.
