Add a filter to the all of the Form Reports to export data/files associated with a specific WBL event

We could really use a way to "Filter" Forms reports, to include the "Event Name" and/or "Event Dates"? This would allow us to save all of the permission slip forms (or export the related data/statuses) for one event. If we do by date range, it does ALL permissions slips and if multiple trips during that time, it makes it really messy.
