Configuring RDS server in ColdFusion Builder?

It was difficult enough trying to configure the datasource (SQL Server 2008 R2) in CF Administrator; SQL Server is configured for Windows authentication only, and I ended up using the advanced options in Administrator to specify a connection string to use.

The config options for RDS servers in CF Builder are very slim; I can only specify a host name/location, port number, timeout value, and user name/password. There are no advanced options as in Administrator; anyone know of any back doors or secret handshakes that will let me configure SQL Server 2008 as an RDS server? TIA!
