We need to update the Create Specialized Question Types help topic and clearly highlight the following usage scenario: 'Create one more component which will look the same as a standard question (e.g., Rating, Dropdown), but with some customized properties.

An example:

creator.toolbox.addItem({
    name: "csat",
    title: "CSAT",
    iconName: "icon-rating",
    isCopied: true,
    id: "csatQuestion",
    category: "General",
    json: {
      type: "rating",
      title: "How satisfied are you with your in-store experience today?",
      rateType: "stars"
    }
});

BTW: in docs, there is no addItem function.
