All issues and child issues associated to an initiative should have the same label. IT1Q2024. I would like to be able to automate the labeling of all child issues. At this time I have to create a specific automation for each new label. IT1Q2024, IT2Q2024, ...etc. It would be more beneficial to have the automation take the label from the current parent: "Initiative" and apply it to all the child issues.
Here is my current automation:

The edit just updates the resulting issues found in the JQL with "IT4Q2023". I have tried using issue.labels smart value in the edit and it just blanks out all the child issues labels. Please assist. TIA!
