How do I control the Story status when Story sub-tasks are ToDo -> Inprogress

[SHANAVASH MOHAMED]

The Story and its sub-tasks in the "Open" status. When I drag a sub-task "ToDo" into the "In Progress" status, how can I cause the parent Story status to change to "In Progress"?

You would need an add-on for it like Power Scripts, ScriptRunner, Automation for Jira, Workflow Toolbox.
