MS Word 2016, I haven't' really messed with footnotes, since they are meant for the end of the page, but there are also endnotes, they put all your footnotes into a single page. So try converting you footnotes to endnotes, right click on the footnote, a menu will appear giving you the choice to convert footnotes to endnotes.
Adding Footnotes and Endnotes A footnote is a short note at the bottom of a page that provides extra information about something mentioned in the regular text on that page. Word indicates a footnote with a reference mark, a number or other symbol that appears as a superscript in both the regular text and in a special footnote box at the bottom of the page. An endnote is similar, except that is appears at the end of the document. Word makes working with footnotes and endnotes a breeze. Not only are they easy to insert, but Word also keeps track of the reference marks and updates the numbers (or whatever) automatically no matter where you insert new notes in the document.
Insert a Footnote or Endnote A default footnote appears at the bottom of the current page and uses Arabic numerals (1, 2, 3, and so on) as the reference marks. A default endnote appears at the end of the document and uses lowercase Roman numerals (i, ii, iii, and so on) as the reference marks. >>>Go Further: Creating Custom Footnotes and Endnotes If Word’s default footnotes and endnotes are not what you need, the program has plenty of options you can wield to customize your notes. For example, you can position the footnote area below the last line of the page instead of at the bottom of the page; for the reference marks, you can use Arabic numerals, uppercase or lowercase letters, uppercase or lowercase Roman numerals, or symbols such as the following: *, †, ‡, §. In fact, you can use any symbol available in the Symbol dialog; you can start the reference marks at a specific number, letter, or symbol; and you can have the reference marks restart with each page or each section. To create a custom footnote or endnote that uses some or all of these options, position the insertion point where you want the reference mark to appear, click Insert, and then click Footnotes.
