Is it possible to not sync two linked issues when the workflow transitions to a specific status? 

There are a couple of statuses where I don't want a sync to occur. We have a status which doesn't really have a corresponding status between JIRA and JSM. I'd like the JIRA status to move to this status, but JSM to stay where it is. JSM can then move statuses when the JIRA ticket moves off of this specific status. 

I have this:

def statusMap = [
def remoteStatusName = replica.status.name
issue.setStatus(statusMap[remoteStatusName] ?: remoteStatusName)

With a load of statuses which I've omitted. 

Any ideas?

Thanks.
