Compare attachments of linked issues

[Nicole Mueller]

Hello community

I have two linked issues and I've added a synchronisation through the automation plugin. I want to copy attachments from one issue to the other as soon as new attachments are added. Now I have used the "Field value changed" trigger and added the Attachment field as fields to monitor.  Now my problem, if a new attachment is added, I only see the possibility to copy all attachments!! This results in a big mess, as if attachments are added more than once, they all get copied every time and not just the newly added ones. There is an "Issue attachments" condition, but it only checks if any attachments exist and not if a certain attachment already exists. Of course I could also delete all attachments of the linked issue and then copy all of them, but this messes up my comments, as a comment is printed for every added attachment. I didn't find any good solution with the automation plugin. Can anyone help me? Thanks a lot!!

Cheers Nicole
