Currently, we can list comments by adding this smart value:

#issue.comments
Comment by: author.displayName at: created
body
/

But if we try to use any kind of conditions inside of smart values, they doesn't apply.

#issue.comments
#if(true)
body
/
/

#issue.comments
#if(author.displayName.endsWith("Automation"))
body
/
/

#issue.comments
#if(not(author.displayName.endsWith("Automation")))
body
/
/

None of the smart values above seemed to work fine.

And we have similar feature for JIRA Cloud that would be good if we had on JIRA Server/DC too.
