Quarterly campaign calendars in a gantt structure - where you can set the period of time to display i.e Jan 1 - March 28. This would show start date of campaign and end date. This will make having to export multiple calendar months to a CVS file obsolete. I can actual create custom campaign calendars by business unit right from Kapost. And in addition to one of the other users comments - you could click on the campaign and it would detail the task/content timelines. Think MS Project but simpler.
