Smart Checklist itself doesn't provide separate storage for checklists templates. However you can use few simple hints to make your life easier with repeatable tasks management.
...
- Use external storage for all templates that you want to use
- Run script that pushes checklist to new item
Use ScriptRunner add-on and JIRA behaviour
If you have ScriptRunner add-on installed on your JIRA instance - set up it in the way, so when you change Issue Type - "Checklists" custom field's content automatically pre-populated to value you set up. E.g.: "definition of done", "acceptance criteria" and so on.
Copy from Email, Slack, Skype. Exchange and share checklists via all possible channels!
