Hello everyone,
In JIRA Automation I have a rule about copying a new comment from an issue (A) to a designated parent issue's field (B).

It works fine, but when 2 (or more) commented issues have the same parent, I only see 1 of the comments (from the issue commented most recently).
I want to append/concatenate comments from multiples issues that have the same parent and display them in the designated field.
Can someone help me?
Thanks
