How do you put an Index Page into a Navigation Folder?

I made several index pages and I wanted to put them into a folder so you can see them in a dropdown in the navigation. I am using the bedford template. I am not seeing any way to do this normally, so is there anyway to do this with custom code?

You cannot drag index pages into a folder, but there's an easy workaround.

First check the URL of the index page then simply add a 'Link' to the navigation folder and enter the URL.
