Is there a way to refresh story points on subtasks that move parent tickets?

[Meghan McPolin]

I have story points on subtasks that automatically refresh totally up to the parent ticket.

If I move a subtask, the story points do not deduct from the old parent and do not update the new parent ticket's story points. Is there a way to automatically refresh the story points?

Background: We are trying to count story points for bugs in each sprint. We want a task to have 40 story points a sprint. Every time a new bug is raised, we want to move the subtask to a new bug and count the points on that bug. This way, the story points should deduct from the tasks and we are not adding more story points to the sprint.

Example:

Original Story Points Summed Up from Subtasks:

1. Parent #1 = 3 story points
   1. Subtask 1- 1 story point
   2. Subtask 2- 1 story point
   3. Subtask 3- 1 story point
2. Parent #2 = 0 story points (no subtask)

----- Move subtask (More --> Move --> update new parent ticket #)

Actual Result: 

1. Parent #1 = 3 story points
   1. Subtask 1- 1 story point
   2. Subtask 2- 1 story point (moved the Parent #2)
   3. Subtask 3- 1 story point
2. Parent #2 = 0 story points (no subtask)
   1. Subtask 2- 1 story point

Expected Result:

1. Parent #1 = 2 story points
   1. Subtask 1- 1 story point
   2. Subtask 2- 1 story point (moved the Parent #2)
   3. Subtask 3- 1 story point
2. Parent #2 = 1 story point (no subtask)
   1. Subtask 2- 1 story point

Summing story points up from sub-tasks is not something Jira does natively (because you don't put sprint estimates like story points on sub-tasks), so when you say "I have story points on subtasks that automatically refresh totally up to the parent ticket.", you or your admins have added something to do it.

You can do the same to cover your need to subtract and add - either create a listener that can pick up the change of parent, or an automation which can subtract from the original and add to the new parent.
