Custom field in Jira service desk that I want to reference in Automation

[Emer McArthur]

Hi - I am trying to copy custom fields from Jira Service Desk project in automation rules so I can create a ticket in Jira Software which includes these custom fields. Is this possible?

Eg new custom field Internal Deadline created and visible in Jira Service Desk ticket

I want to create a Jira Software ticket that includes this field 

And auto close the Jira Service Desk ticket

I have tried ${sourceissue.internaldeadline}

This would require add ons as it's not possible to automatically copy custom fields currently
