Posts in Page – How to customize the URL?

The only way I can see this working is by setting a couple of redirect rules in your .htaccess file. You’d have to manually redirect all your posts (that you want with that permalink structure) and prepend the /awesome URL part in front.

Other than the aforementioned solution, which is a hack more than anything, I’m afraid that what you’re looking for is not possible. As @Florian Grell said above, this is a behaviour best suited for categories rather than pages.
