CTA Due Date should reflect due date of next open Task in Playbook

For CTAs with Playbooks, the CTA due date defaults to the due date of the last Task in the Playbook series.  It would be helpful if the CTA Due Date could reflect the next Task due in the series of Tasks.  

If Cockpit is sorted by Due Date, end-users can essentially now see their list of Tasks in chronological order vs having to expand the Tasks and filter through them to see which ones are coming due.
