Parent Task to Display Sum of Subtask


Is there a way for the parent task to display the sum of its subtasks?

As you can see Image 1, if I were to hide all the subtasks, it looks like the parent task has no value.

I would like the parent task to automatically display the sum of its subtasks (see image 2).

Note: If I were to manually input the total value of the subtasks into the parent task (without removing the values in the subtasks), the final sum at the bottom of the section would add the value of the parent task and its subtasks, which is not the correct representation (see image 3).

Please advise. Thank you in advance!
