This be done with a custom script tailored to your workflow.
Since InDesign Articles are linked to pages (rather they're linked to a series of stories that can span multiple pages), there isn't a good "one size fits all" way to approach this via the Articles panel.
However, another approach might be to name each page with an InDesign Bookmark.
If you make any changes in the Resources section of the in5 dialog (even just clicking one of the "append" buttons), in5 will export a bit of extra metadata, including a data-bookmarks attribute on the "page" node that will include any bookmark names on that page.
