I need to create footnotes that automatically update to look to other footnotes.
For example: Thompson, supra note 4 (and have 4 be a cross reference).
The issue is that each footnote has tons of sources and I want it to update according to a specific part of a previous footnote and move with that text. However, adding a bookmark does not allow an option to cite to the bookmark's footnote. How can I fix this issue?

For example:
Footnote 2: See CA Masten, “One Man Companies and Their Controlling Shareholders” (1936) 14:8 Can Bar Rev 663; Mervyn Woods, “Lifting the Corporate Veil in Canada” (1957) 35:10 Can Bar Rev 1176; GT Tamaki, “Lifting the Corporate Veil in Canadian Income Tax Law” (1962) 8:3 McGill LJ 159; WJA Mitchell, “Taxation and the Corporate Veil” (1966) 14 Can Tax J 534 [Mitchell, “Taxation”];

Footnote 3: Woods, supra note 2. (how do I get it to follow the woods text?)

You can add cross-references to footnotes via the Cross-reference dialog box in Word (References tab | Cross-reference). Note that the references update semi-automatically; to force an update you can switch to Print Preview (Ctrl+F2) and then return to your previous view (ESC).

Edit: I realize that you want to update the content of footnote 2 in your example to match part of the content in footnote 1. If you bookmark the relevant text in footnote 1 and insert a cross-reference to bookmark text in footnote 2, you can then use the keyboard shortcuts mentioned above to keep the reference updated.
