I have team who updates story point on weekly basis on issues in jira. if this week they have a task called AB and the story point updated is 5 and next week story point updated will be 8 and the next week actually story points spent will be 3, so total as of week 2 is 8 if I want the individual value when it is updated, how can I automate that is jira without created any new field every time they update the story point I should get a weekly report by Friday as to how many story points are added and what was the previous value
