Aggregate report for RSS individual session webforms

Is it possible to get an aggregate report for all webforms (post-activity surveys) done as part of an RSS session? We have some series that do an eval after every session, as part of the requirement to get credit. They would like to see their data in aggregate, rather than having to download an individual report for each session. Has anyone been able to solve this problem already? Thanks!


I haven’t been able to solve this problem for our conferences/multi-session events and am very interested in a solution!
