In a Prodigy System it adds the two zone volume extender by default. You can go into the properties of the device and disable the check box under devices if you don't want to use the extender. The two zone volume extender is pretty cool when you figure it out. kind of like an Interlock source select if you know what I mean. You can base your Presets from the extender feedback. ex On the extender: On source Cable Box selected Fb, you could then add you preset for cable select.
