What I have now:

It's a simple rule: if the issue is moved to the review state by user_x, add a comment with specified text.
I have the template of the text saved in another Jira issue. When I need to make changes in the text, I need to change it both in the static template issue and the automation rule.
Is it possible to copy the content of the description field of Jira issue XX-YYYY when I add a comment to the issue that triggered automation? We are using Jira cloud.
