Make Entire Button Area Clickable (buttons, RSVP, poll block)

My clients are often confused when they click an RSVP button and nothing happens. The end result is that they mistaking think they have RSVP'd to an event when actually nothing has happened. This is caused by the RSVP buttons which look like buttons but only contain hyperlink text near the center. Can Constant Contact development team make the entire RSVP button (which appears to be an HTML table cell) an active click area?
