Currently, one has the option either to create a report from one or more selected folders, OR to create a report from selected questions within a single folder. However, when teaching, it's not always possible to get through all the intended material in a given session, so sometimes a particular class will cover the end of one topic and the beginning of another topic. If one is (reasonably) sorting polling questions into folders by topic, there's a good chance that one will need to generate a report for a particular day that includes some polls from folder A and other polls from folder B. As things stand, that's impossible (unless I've missed a feature).

The other approach would be to allow individual poll questions to be deleted from a report, since then one could simply select the relevant folders en masse, and then delete from the generated report the questions that weren't asked on a given day. (Again, I don't believe this is currently possible.)
