I'd like to specify (part of) the subtask ID. Using JIRA for bug tracking and sometimes a bug must be fixed on multiple branches. I'd like to use subtasks to specify the different branches. Unfortunately, our developers can get confused by different issue IDs so I'd like have subtasks inherit the parents' ID. Something like parent ID is 5000, subtask 1 is 5000.1, subtask 2 is 5000.2.
Is there a way to achieve this?
