.NET package ... TN Pool

I am trying to figure out how to access the TN Pool from C# … under the IS -> Settings -> JDBC Pools you can test the TN Pool connection and also edit the TN Pool connection to change the password. This process, along with the other areas of the application, seems to complex for our field users so I am creating a Client app that allows them to change all passwords in one spot. I can find all the services to access the custom connections, and the wmDB connections, and I’ve even found wm.tn.admin:getDBPoolInfo which returns some values including the connection status. But I cannot find the service that will allow me to update the password … any assistance you can provide is appreciated!
