Hi slfoster! If you have not yet already, we'd recommend posting this as a new idea in our Product Ideas category, as it not currently possible. The export will include all new responses since the last export by default with no filter applied. There’s not a way to pick and choose what gets included, unfortunately, as the best filter that we can apply would be “(Question) - (is not empty)“, but that would include the whole response if they qualified. If you have any follow up questions, be sure to reach out to our wonderful Support team!
