You can select and merge multiple attributes in the output schema to create a new output attribute that has the original attributes as its sub-attributes. For example, you have two attributes in the output schema: House Number and Street. You can merge these to create a new attribute called Address which will have House Number and Street as its sub-attributes.
Note: This method can only be used on attributes that are not inherited.
