Currently when you export data, if a story has been part of multiple sprints, the export lists each sprint as an individual field - this makes automated processing of the export file very difficult.

What would be required is to export a single "Latest Sprint" field that contains only the latest sprint for any record, or blank if it has never been allocated to a sprint.

Additional to that, it would also make sense to make the "Latest Sprint" field available in the issue filter, since multiple past sprints in the same field make it difficult to see what is the current active sprint of the issues.
