Some of our features as massive, they will require hundreds of hours of work, far too much for a single sprint. What i'd like to do is create a milestone called 'Diary' in that we would have many stories outlining smaller stories outlining each feature and sub-tasks outlining the exact work. The idea would be I can allocate 5 of these smaller stories to a sprint whilst still keeping the progress of the whole 'diary' milestone. Is there something like 'Milestones'? I've not been able to find them.
