Automation > Find a Blogs, Comment, Parent

[Ken]

I'm trying to run an automation to do the following

Send email notification 
When a blogpost is created
Only when the user is in a group ( I can do this )
When the comment is not a reply ( I cannot do this )

Is there a way in automation, with SmartValues or CQL to be able to get to {{comment.parent}} IS EMPTY  ?

Here is all the properties of the "comment" entity that are exposed as smart values:

It seems there is no property to decide if the comment was a reply.
