Absolutely! If you're looking to replace those post-session surveys, or you just want to apply a question to several sessions, you can use the Session Feedback survey type to do so. When creating the survey you can apply the questions you're creating to All Sessions, Tracks, or a Selected Sessions.
You can create four types of questions: Rating, Text, Select One, and a Select Multiple. These questions will be embedded within session pages on the app, as opposed to live polls which are linked to at the bottom of session pages.
