I am working with a word document where I have 6 endnotes/sources that
refer to one sentence.  Instead of listing each endnote as a
superscript, is it possible to have a reference like 1-6 in the
superscript.  This may sound confusing so here is a visual example:

This is my example 1 2 3 4 5 6. (numbers would be superscripted as
endnotes)

1 endnote 1
2 endnote 2
3 endnote 3
4 endnote 4
5 endnote 5
6 endnote 6

My desired result would be:

This is my example 1-6.  (numbers would be superscripted as endnotes)

Any help is greatly appreciated.
