@Brandon G Query fields should allow you to extract the required fields in the response of the analyze operation along with the regular structure of the model that you are using. For example, a layout operation where I added 2 query fields Name and Remark provides them in the response in the fields object of the response.
If you are referring to altering the output structure, then I think that is not possible. The query fields are simply added to the fields object in the response.
