I want the word 'Notes' to appear in my Heading 1 style directly above my Endnotes.

Endnotes have a nasty habit of wanting their own page. I can get around this by placing 'Notes' in the Endnotes separator box.

But I cannot get 'Notes' to show up on the Table of Contents.

Is there a way to edit the Endnotes style directly to allow text on the Endnotes page? Or perhaps through a header, although I can't seem to add one to the Endnotes page either. Google tells me there is a way to enable the Header on the Endnote page, but I can't find it in Word 2013.
