Aggregating data from multiple Trello boards
Sometimes you might want to see aggregated metrics over multiple Trello boards. For example, you might want to consolidate status updates from multiple teams into the same Team Status screen, or to track cycle times over multiple Trello boards.
To create an aggregate screen, go to the Sources tab in the chart settings. You'll see a list of data sources that can be selected as a data source for this screen. These are your Screenful dashboards that you have created for your Trello boards.
