Spotlight on SQL Server Enterprise - How can I modify an existing database connection to include a port number?

We recently disabled the named pipes provider for our SQL Servers and now Spotlight is timing out on connection now. I want to modify the existing connections in spotlight to include our custom port number so that we do not lose any monitoring history. However when I open the connection properties in Spotlight the Address field is greyed out and cannot be modified.
