When creating or editing a task list, under the 'Defaults' tab you can set values to be applied to any tasks that are added to your task list. 

The options are:

  • Assignee
  • Start Date
  • Due Date
  • Description
  • Followers
  • Privacy
  • Estimated Time
  • Priority
  • Tags
  • Board Columns
  • Estimated Time

Just click the 'Edit' link and you'll see a screen just like the task form where you can set the default values.

Please note - tasks created by email will also inherit the default values unless you specify different values using task-by-email commands
