How to find projects with no assigned, dated tasks?


My team uses Asana to track a large number of simultaneous projects, some of which sit idle for long periods of time (up to a year in some cases). However in each case we want to make sure that each project has at least one task that is assigned to an individual, and has a due date.

Is there a way to run a report to show any project which does not have an assigned task with a due date?
