As far as your question, if your links are normal HTML text links, then they can all go in the same box. If you are making graphic boxes filled with the link text, then make separate boxes and link the entire box using the Hyperlink dialog or the “globe” picker at the bottom of the Freeway document window. Even though you can highlight a run of graphic text and link individual words in that manner, it’s a bit of a hack.
