Hi Daniel,
It depends on what you mean by "customize". The text of the Welcome tile in SAS Home cannot be customized. However, an administrator can customize the list of shared links that are available in SAS Home. An administrator can also publish a collection, which is a group of favorites, for users. There's information about these tasks available in the online Help that ships with SAS Home 7.3.
If you're using SAS Visual Analytics 7.2 or earlier, the information about shared links and collections is available in the SAS Visual Analytics User's Guide. The various editions are available from the SAS Visual Analytics documentation page.
Hope this helps,
Joy
