two SW installs vs two Excel installs

Hi
I have on my system SolidWorks 2007 and SolidWorks 2008 and also Ihave Office 2003 and Office 2007

I wonder if it possible "to tell" to SolidWorks 2007 to use Excel2003 and for SolidWorks 2008 to use Excel 2007 when I use DesignTable functionality.

thank youSolidworksConfigurations design Tables
