We have about 180 databases across 6 servers now, and they are constantly changing with new databases and servers being added! The utility mentioned is not nearly enough to keep up with this.
I ended up writing a .NET application that builds the distribution list XML file that Multi Script uses each time it runs. Gives me exact control over building the lists I need in different ways. Also allows me to order the database list based on server so it will execute all scripts on all servers at once (since Multi Script seriosly lacks the option for parallel execution across servers instead of databases)
I posted the code to generate the list at:
