It seems like survey invitations which include a question (perhaps the first and/or most important question) are becoming more popular in the industry. I have attached an example. Once you click one of the buttons to answer that question, it opens the remainder of the survey. After a search of the forums and manual, it doesn't appear this has been addressed before. Perhaps it could easily be done with buttons, scripts, and equations without being an actual feature of LS. But since it is becoming more popular, maybe it is worth considering?
