A common requirement for SharePoint Content Aggregation is to perform a SharePoint Task Rollup. You can rollup SharePoint Tasks easily using the Lightning Conductor from within a site collection or across multiple site collections or web applications. When configuring your SharePoint Task Rollup with the Lightning Conductor, you could consider grouping by multiple columns such as Task Status, and Task Priority. Conditional Formatting is also beneficial within the Lightning Conductor when performing a Task Rollup as you can very easily highlight list items such as those tasks that are assigned to you or marked as high priority.
