[Observium] Disable email notification every 5 minutes

Hello

I installed the latest CE (0.16.1.7533) and set up some alerts with email notification.

It is working great, but now i get lot of mails in every 5 minutes from the same alerts.

Can i set up that get email only when the alarm caused or resolved? So just 2 mails (or get mails in X minutes (e.g. In every 1 hors) not in every 5 minutes?

Thanks!
