I figured this would be a rather simple option, but after fervent googling I couldn't find a good answer.
I have a script that automatically creates Parent tasks and then sub-tasks for that Parent. Imagine the Parent task is a Book and the sub-tasks are its Chapters.
Usually, in my workflow, the users assign themselves to the Parent and then they start working on the sub-tasks since they are the only things that matter - the Parent task is just used for navigation.
However, I'd like the sub-tasks to be assigned to that user the same moment he or she assigns themselves to the Parent. So, they assign themselves to the Parent and the sub-tasks are also automatically assigned as well.
Do you think there is such a possibility? Thanks!
Note: I cannot use any plugins such as Automation for JIRA
