There is a (rather inelegant) way to do this, if you've got a decent web browser. Create a folder on your browser bar. Open each forum you'd like to peruse, and save that page as a bookmark to the created folder. When you're done, set that folder to open automatically on launch, and each bookmark will open in its own tab with the most current post in that forum at the top.
That way, you only open the forums you want to see, and not be bothered with those you don't want to see.
Like I said, rather inelegant, but it works, and could be a stopgap measure until the software is updated or changed.
