Updating an exisitng language in Drupal 6

Joined: 02/17/2008

Hey guys, I have searched around and cannot seem to find an answer for this, but does anyone know how I can update an already installed language in Drupal 6?

I have Brazilian Portuguese installed but there is a new version available. I know that in Admin -> Site Building -> Translate Interface -> Import you can individual add .po files, but that seems like a lot of work. Does anyone know if there is a way I can bulk import these files without having to dig them out one by one?

Thanks
Jason
