Embedded Fields - Search Query

I’m populating some entities with a crawler and connector. As part of that, I send the URL to a specific field. In addition, I have another field that uses embedded fields to combine the URL with a string for tracking, e.g., utm_source=websitename.com&utm_medium=referral&utm_campaign=websitename+site+search. I’d love to also include the query the user used to search. The idea here is to append “&utm_content=[[query the user typed]]” to the query string. As far as I can tell, there is no embedded field for query.

Is there a better way to accomplish this? Will I have to append that parameter when we render the results from the response we get from Yext or is there a way to do this within the KnowledgeGraph or Answers configurations?
