Rt-crontool send email to watchers but not log event

I’m trying to do something similar to the Reminders notification via rt-crontool:

But instead of notifying an owner of their reminder, I want to notify the queue watchers (and owner, but that’s less important) when a ticket hasn’t been touched in some time period.

The problem is, I can’t figure out how to make it notify the watchers using the above example.

The alternative method I found was to log a comment, but if I do that, that updates the ticket LastUpdated, which is what I’m searching against, which resets the clock.

A much more complicated setup could/would be achieved using the SLA extension, which is where I may end up having to go, but was hoping to knock this out quickly.

Thanks,
Brent
