How do I sum the original estimates of all the linked Tasks under a Story?

[Abhishek]

Consider the following scenarios:

• Story A
  • Task 1
  • Task 2
  • Task 3

Where three tasks are linked under one story. I am trying to figure out a way to automate the calculation for Original estimates of Story A. Every time a ticket is linked to the story OR every time the original estimate is updated of one of the linked tasks, I want to update the Original Estimate(OE) of the story as:
OE of Task 1 + OE of Task 2 + OE of Task 3

Any leads on how to achieve this will be appreciated!
