Hierarchical Outage notifications?

[FatalXcepti0n]

Hi,
I am verynew to Cacti, so apologies if this is a green question... Is it possible to setup alerts in a hierarchy? My example is, in a multiple-site scenario, if a router for a site goes down, can I just get the alert for the router, and not the 100 other devices at that location? The way I see the logic working is, if the router (A) loses connection, then don't send further alerts for devices under A in the hierarchy (a, b, c, d, etc.) until the alarm state for A restores.
Is this functionality available in Cacti?

Thanks!
