I have a document with endnotes. After inserting a new endnote (i.e. endnote 20) I need to refer to that same endnote later in the text (i.e. after creating endnotes 21, 21, 23, etc.).

I don't want a new endnote, and I don't want to duplicate endnotes. I need to insert a reference to a previous endnote that will be automatically updated if I insert a new endnote before the first use of endnote 20 (i.e. if a new endnote 10 is inserted).

Does Word 2007 have a feature to refer to an existing endnote?

Thanks.
