WHAT DO YOU RECOMMEND
Add “Links to” and “Links from” default relations to Task type.
HOW COULD IT BE DONE
When a task is added on a page, the “Links to” and “Links from” the task object are automatically created and entered in the task relations fields.
REAL WORLD USE CASES
The “Links to” and “Links from” relations can be displayed in Set of Tasks to show task parents and children. Feature Enhancement: Indent sub tasks under parent tasks in the Set of Task views.
Workaround: Create and enter task links relations manually for display in Sets of Tasks.
