I know this is something that I've done in other PM software, such as Asana. It's a helpful feature when the owners of a part of the project want to get really granular in their task management but that granularity doesn't need to be in the larger project.

We have received a lot of feedback that our users find the integration between the Workfront and Outlook calendars limited because you have to manually move the tasks over. Our request is that tasks automatically show up on the outlook calendar on the date the task is due, as all day events.
