Injecting hotfixes to Offline Updater

Hello everyone,
is there any way how to inject any hotfix (*.msp, *.msu or *.cab) file into offline updater after it has created it's repository?
I'm specifically interested in W2K8 R2 enterprise hotfix rollup and it's three subsequent hotfixes:

Thanks a lot for any answer!
