How to add more location to a task:
1 - Open the task and its properties window
2 - Click on the "+" icon next to the “Location” tab.
3 - Select a project and a tasklist where you'd like to add the task.
4 - Hit Add New Location.
5 - You can remove a task location by clicking on the "x" icon next to it.
NOTE:
A Task can exist in multiple locations only between Public projects or Private projects with Full Access permission setting.
Optional: Adding location for all of its subtasks. If not selected, the subtasks/checklists will still appear in the alternative location, but the subtask will show its source project as an actual location.
Only task properties are kept, comments and files are not included.
