Is there a way (or plugin) to create a sub-tasks for multiple stories at once (as bulk action)

[Deleted user]

I have 10 stories, I need each story to have a sub-tasks. Is there a way to create sub-tasks in bulk?

(and also assign them a label and maybe a name pattern)

Automation samples

On transition

   issue type = story

   create subtask with summary of (Insert static text) for {{smart value}}.

On creation

  issue type = story

  refetch issue data

  Create subtask with summary (insert static text) for {{smartvalue}}

Hi @[deleted] ,

Welcome to the community!

Have a look at Create on Transition for Jira 

If you are well versed with automations you can refer: https://www.atlassian.com/agile/tutorials/how-to-auto-create-subtasks-with-jira-software-automation 

Good Luck!
