Changing DIV container to another block

I'm trying to figure out if this is possible in the editor without resorting to HTML source editing.

I have a CSS style for visually breaking up an article. Typically this is rendered as divider lines bewteen each section of an article. The style also applies a clearfix technique to keep floated images from flowing into other parts of the document. The style is defined in addStyleSet like so:

CKEDITOR.addStylesSet('cgr_styles',
    [
      {
        name: 'Section (div)',
        element: 'div',
        attributes: {'class' : 'article-section'}
      },
      {
        name: 'Section (section)',
        element: 'section',
        attributes: {'class' : 'article-section'}
      },
    ]
);

So with the insert DIV button its pretty simple to wrap a bunch of elements (headers, paragraphs) inside a <div> container and set the <div> to use the 'article-section' class. So I might end up with HTML like the following:

<div class="article-section">
  <h2>The sub-heading</h2>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    Aenean tincidunt ligula erat, in laoreet turpis tincidunt sit amet.
    Praesent lacinia justo ut ante sodales rutrum.
  </p>
</div>

However. Most of the time it is sematically better to use a <section> tag (or another block like header or aside). So I think this would be as simple as clicking the <div> element using the tag breadcrumb. E.g. "body div". Then either choosing <section> from the Block list of choosing 'Section (section)' from the Styles list. But instead of changing the <div> to a <section>, it changes all the child elements to a <section> and the original <div> remains untouched.

I can change the <div> tag in source view to a <section> but that is not very user friendly. Can what I explained be achieved using the editor's tools so I end up with the final output looking like:

<section class="article-section">
  <h2>The sub-heading</h2>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    Aenean tincidunt ligula erat, in laoreet turpis tincidunt sit amet.
    Praesent lacinia justo ut ante sodales rutrum.
  </p>
</section>
