Including and already downloaded update

Hi all, and thanks for this great tool,
I got a question on how to include to the updates dowloaded by WSUS Offline an update I downloaded before. More clearly, I already downloaded Office 2010 SP1 Fra, and as my internet connection is very slow and unstable (living in Democratic Republic of Congo...) i would like to know if it is possible to include that SP to the files dowloaded by WSUS in order to include it in the iso that will be built.
Thanks for answer,
