I have had a number of users come to me and ask if there was a way to have more than project, issue security level, and sprint value be inherited from the parent task when createing a sub task. I have found nothing on the subject except this excerpt in the help documentation:
Note that when you create a sub-task, the following values are inherited from the parent task: · project · issue security level · sprint value, if any (only for JIRA Software issues)
If anyone has any ideas that would help with this, please let me know.
