In SAFe Epics are broken down into Capabilities, which break down into Features, which break down into Stories. At each level of the hierarchy the information of child artifacts are aggregated for visibility. As such V1 should make it possible to look at an Epic and see information related to blockers attached to stories which are in the decomposition lineage of that Epic. Currently it is possible to go one level up on the hierarchy and see a "roll up blocking blockers" as a number, but not any kind of detail. In order for an Epic owner to understand what Blockers are related to their Epic they have to drill down to the level that the blocker is attached. This information should be available through the main system and in analytics.
