Make Default News Item DX Folderish

Plone Support Add-on Development
1

I want to be able to add a file to the default News Item Content-Type, is there a way to override the default types definition or to make it folderish..?

I've been looking at the plone.app.contenttypes documentation for extending the Content-Type but I don't see where to go with this.

Cheers for the help!

So it seems the collective.folderishtypes offers the functionality that I need...

Edit:

I added the following to me metadata.xml:

<dependencies>
    <dependency>profile-collective.folderishtypes.dx:default</dependency>
</dependencies>

you may also use the collective.nitf content type instead; you can have images, files and links inside of it and it has 3 or 4 views.

we're using it in all our news and government sites (just note we'll be refactoring some parts of it in the following weeks).
