How to add multiple checklists to one Jira issue with Automation

Navigate to the project automation section of your Jira project. If you are a Jira admin, you can do this from the global automation administration page.
Click “Create rule.”
Choose the trigger which you would like to start this automation with. In our example, we will use the “Issue transitioned” trigger.
If you’d like to add any conditions, you can do that now as well.
For the automation action, choose the “Set entity property” action.
In the “Property key” field, add the text “didit.action”. Please note that the “didit.action” property is case sensitive.
For the “Property value,” you can either use Markdown to set an ad-hoc checklist or JSON to add a checklist from a template.
For examples on Markdown and JSON, please visit our Jira automation examples page.
Repeat steps 5-7 in the same rule with as many different actions as checklists you would like. Our example below shows adding two checklists.
