The Grapevine post-purchase survey question is intended to be a quick and easy single survey question for your customers to answer immediately after they have made a purchase on your store.
We have been discussing adding the ability to add more questions and archive questions, but as yet, we have not taken the decision to do so.
We feel that Customers are keen to go about their business once they've placed an order, so keeping the survey simple should make it more likely for them to submit an answer.
