Is your feature request related to a problem? 😢 Please describe.
I have say some 6 or 7 subtasks under a parent task and I define efforts to those subtasks. Currently, I have to manually add up the efforts each time I create a parent and subtasks under it.

Describe the solution you'd like 🤔
It would be good, if those efforts on the subtask gets added and displayed on the parent task.

Describe alternatives you've considered 🧐
NA - I manually add the efforts and put on the parent task.

Additional context 📝

Miscellaneous
Conditions to take care of:

• The calculation of efforts applies only if a task is a parent type. For single tasks no action.
• Tasks with no efforts to be considered zero (0) for calculation.
