Is there a way to go to the first unread post on a thread?

[TKDmom]

When I come back to read new replies on a thread that I have previously read, is there any way to just go directly to the first unread post? I have been scrolling down to figure out which posts I've already read, but it would be so much more convenient to have a button at the top of the thread that says "view first unread" or something like that.
