Links inside Folders

Maybe Webflow already has this or maybe there is a way around this. I wish that if we created a folder and named it “about” for example sake. When we created a page in that folder it would auto default to make the index page live inside that folder so that all you would have to type is www.website.com/about and the about page would load instead of linking it to www.website.com/about/about.html.

Does this already exist? Am I missing something?

Thanks Guys,
