I just stared using Portfolio 2.0, I used the wizard to connect it to our Board. We have Sprints on the Board that are serving to group Stories for purposes other than scheduling into a release. They're used as holding buckets to easily remember which Stories were deferred from a Release. The Stories in each of these "non Sprint" Sprints may be in many Epics. Is there any way to suppress these non-Sprint Sprints from coming into Portfolio? I tried emptying one and then deleting it from the Board, but it is still showing in Portfolio.
