update original time estimate on story according to the time estimation of the subtasks +

[Eleanor]

Hi guys :) 
I have 2 issues that I would like you to help me with:

1. Our team is working with Original estimation. When we add subtasks to a story, and each subtask has its own Original time estimation, how can we reflect that on the story's Original estimation? (not manually but automatically sum the subtasks estimation and add it to the story Original estimation).

2. Second thing is the view of the Original time estimation + remaining time + issues num, per assignee in the backlog. 
currently it doesn't show the correct Original time estimation, it doesn't include the estimation of the sub-tasks.
also, if a story for example has a time estimation of 2 days and assigned to person A, but has sub-tasks that are assigned also to person B, then person A gets 2 days in the time estimation in the backlog, and person B gets 0 days. 
now, this is wrong for our team, because we want to see it according to the sub-tasks. and if a story/task doesn't have the sub-tasks then according to the story/task time.

Welcome to the Atlassian Community!

Jira already does this automatically - if you look at an issue, the time-tracking section has a flag for "display total estimates or ignore sub-task estimates"

You can't do this by user, that does not make any sense when you're looking at estimates.

Also, in a backlog, that implies you are using a Scrum or Kanban board.  Sub-task estimates are not useful in a backlog in either of these methodologies.   In Kanban, the estimate is irrelevant because all issues are the same size - it measures throughput. In Scrum, the estimate on a sub-task is irrelevant because they are fragments of sprint items, not sprint items themselves.
