Page title displaying topic subject first then forum title

Hello All,
Using Punbb for a few months already, I would like to know if there is any chance to get a configuration option allowing me to place the topic subject at the first position in the page title instead of the forum name.
The idea is to give search engines a better description of what the page content is, instead of sending always the board title first and then the topic desctription. It makes a difference in Google where only the first characters are displayed in a result page and, if the board title is long, there is no place for displaying the topic subject which is what people are searching for, at least I guess.

I modified the code in the viewforum.php and viewtopic.php pages to invert the two varaibles doing this (see http://forum.nikonpassion.com) but I do care about code modification, so it would be great to have a config option to do so.
Is that clear ?
