In RTC 2.0.0.2 is there a way to refine a PLAN so that we can focus on a work item category that's subordinate to a TEAM? And can PLANS be related to a query rather than just a single team? We have work item categories that are nested under parent work item categories, and these nested categories are related to the parent TEAM at a higher level. Can we create a plan specific to a work item category that doesn't present all the work items for the parent TEAM?
