Office 2003 Updates WITHOUT re-installing office after an administrative install

[Saucer Man]

Is there anyway to install just the needed updates to an
Office 2003 installation that was done from an
administrative install point WITHOUT updating the point
and re-installing office on the clients?

I just want to create an administrative install point to
do my initial installs. After that, I want to install
just the needed patches and/or Service Packs via somthing
like SUS. I don't want to update the administrative
install point and re-install office everytime. Thanks.
