I have a custom Fix version (Custom Field for text) in Jira that is filled by API automatically but I want the same data to auto populate on the Normal Fix Version field in my Jira cloud instance when the issue is in progress or being transitioned to done, I want the custom field data to auto populate on the fix version field with same data if Fix version is empty that is.
Summary:
1. Data from Custom field - Fix Version filled by API automatically.
2. Same data to Auto Populate to system Fix Version field on Transition of same issue to in progress or in done status.
