Is there a way to deploy an Office language after installation?

[sidewinder]

God knows how it has happened, but the version of Office 2010 we have deployed, while having English as the editing language, has nothing installed as the proofing language, so no spellchecking can be done! (I'm quite annoyed by this as it is, I followed all the steps to customise the install, why was this not part of it?)

 

I've found plenty of documentation about adding languages to the initial install, but obviously I dont want to reinstall it over 900 times just for a language install! Or would setup be clever enough to realise that was the only change? The documentation I have mentions using the config.xml file, is this the best method?
