Like with other type of alert targets (Send to), we would like to be able to resend an alert to PagerDuty.

The reason is that an alert sent to PagerDuty can be mistakenly resolved but the real issue is still there, and the alert is still firing in Atlas.

Because it is already firing, it won't fire again so from that moment on, there is no way to get a notification of that alert so we might be missing a real issue.
