Scroll to unread posts?

Is there a setting so that when I open a thread I've viewed before, it'll automatically scroll to the first unread reply? As is, it'll go to the right page in the thread, but opens at the top of the page even if I've seen that reply. It's something that's on most boards I've been on, so I don't know if there's a setting I'm missing or just something not available on this board.
