Buttons Question

On my new all-Flash site I need a long list of text links. I’m building the site right now and for the list of links, I just have them all as one text box. Do I need to have make every single link a button symbol in order to have it rollover? I know I can keep them as one body of text and put invisible buttons on a layer above them, but I don’t think I can make them rollover that way. Is there a shortcut to doing this other than making 30 different text buttons?
