Not any built-in way, no. And probably not likely to be added, as it would require a mod to SMF, which is not something that is going to happen here unless it's important. Which this is not.
That being said, and depending on your browser, there are ways to roll your own. Check the forum archives for a Greasemonkey script I wrote a year or two ago that does what you're asking. IIRC, it will work in Firefox and, with some slight adjustments, Safari and IE as well.
