I think this requires customization on your end ...

I had to customized mine so that it would grabs all the information from a database, therefore it knows which pages to display and save from each page's ID # ...

If you are editing static pages in a folder, then I think you might have to create an interface to display these html files, set a variable for each file, like use the file name as the variable, then create an edit function that will identify each page by the variables that is set for it, pass the variable to the editor so it will know which page to pull up and save ..

I'm sure there's alot more to it, but this is just off the top of my head ...

Hope that helps :)
