In our enterprise we need a way to quickly identify Portfolio Items that are lingering in any given status. Currently on the Portfolio Item Kanban Board, you can set WIP limits but not Cycle Time Threshold, or even quickly hover over the "clock"icon as you can do on Story Boards to see how long something has been in-flight. This is an essential need when you have a heavily populated Kanban Board where you need to draw people's attention quickly to problems. Ideally, a filter setting that will allow you to filter by any Portfolio Item exceeding its threshold would be great. We currently do a similar thing where you can currently filter by Blocking Issues greater than 0. Having both of these capabilities in unison would help our leadership zoom in on issues in a sea of PIs quicker.
