I am setting up a template for a book design that I've been working on, and I am trying to figure out the best way to format the side notes. I have them set as a numbered bullet, and each one will be in its own text box but all the text boxes will be linked so the numbers will go in order. I want to anchor each side note text box to run with the corresponding number (see the attachment). Chances are, the copy is going to move around so I want to make sure the side notes are linked somehow to their number to avoid having to go through and find them later on. What's the best way to do this?
