I understand how to add additional downloads to the StaticDownloadLinks... file and to the StaticUpdateIds... file so they get downloaded and installed by Wsus Offline Update, and how to locate the full download link for things in the Microsoft Download Center (http://www.microsoft.com/en-us/download/).
But for something, such as hotfix KB3001554, that is only available on the Microsoft Update Catalog (https://catalog.update.microsoft.com/), how do I find the full download link to put in StaticDownloadLinks...?
