JSONFlattener w/ Arguments

Hello: I have a surveymonkey survey responses that I have to loop through to capture all of the responses from 1 page. I capture the number of responses from an attribute returned from the GET from the API endpoint and I use that as my loop counter. My question is can I loop through the response body and pass the loop counter to capture the next survey response on this page? For instance, if I have data{}.id as an attribute, in a JSONFlattener can I dynamically set the value within the {} to @Value_count? Any help is greatly appreciated.
