Does anyone change SLD information via scripts?

Hello,

    I have a need to make a change to a SAP PI environment twice a day, in order that two different ECC systems can be utilized by a single PI system for development and regression testing.  

    Currently I make the change manually:

          SAP SLD -> Business System -> Integration -> Technical System ( change ).

    Does anyone know of a way to make such a change remotely via a script?

    I know there is a Fast Switch document for updating the PI Comm Channels remotely, but I can't find a way to do this in a script or code, etc...

    Any help or advice is greatly appreciated.

    Thanks,

Mike
