I would like this feature because I am using subtasks as actions to complete Tasks (deliverables) and I would like to build a card that reports all the Subtasks (actions) grouped by Start Date (which does not see to be available either) and then sorted by Start Date (w/time of day). That would give our team a powerful card to show them what to work on (actions) when each day. This would be very efficient.

I think this is related, I think I just need a filter on widgets to only show subtasks. This is relevant for us as we use tasks to represent "epics" which span any amount of time, and it's really the subtasks that represent the actual work we're doing. So for Lead Time and Cycle Time metrics, filtering by subtask is what matters.

This will be very helpful to improve visibility and reporting!!!

we desperately need this as well!

We would like the ability to include nested subtasks from multiple lists in filters and widget calculations in dashboards.

Having the ability to report on overdue subtasks as well on the Who's Behind Widget
