How can I send a message to all of the linked Service Desk tickets?

[Drew Angell]

I have a Jira ticket with a bunch of linked Service Desk tickets.  I would like to send the same message to all of these linked Service Desk customers.  

Is there any way to get this done through Automation or any other trick? 

I was trying to run a query that would return all the linked tickets, but I'm struggling to find JQL that will do that.

Any information on this would be greatly appreciated.  Thanks!

EDIT:  It looks like this might do the trick:  issue in linkedIssues(pfw-1040)

This worked to query the tickets:  issue in linkedIssues(pfw-1040)

Then I did a bulk update to add the reply to customer comment.
