I'm not familiar with the Zenworks version of AS, however, I'm assuming this piece of functionality is the same.
Use the Editor to create the transform (File->New, Transform). Run the response transform if you need to. Go to System Configuration-->INI File Changes and right-click to create a new entry. Right-click to create a section reference and right-click again to create a value name reference. Fill in the value for value data and you should be set. Save the transform and give it a spin.
