To keep the data unique and dynamic to avoid duplication and similarity, you can supply spin formatted syntax. in the data fields where applicable.
Input fields are appended to the data settings screen as new engine types you choose are added. For example, if you choose Blog comment engine types, an additional field named Blog Comment will appear for you to fill in.
