Notifikation request

Hi all
first of all i want to say that i really am an icinga newbie, and that i have been in the icinga world for about 1 month.

My scenario is: user1 gets notikation only once user2 gets notifikation in intervals of 1 hour
is it possible to change in director that both users get every 60 minutes .
Notification

user2
Imports
mail-service-notification
Users
user2
User groups Apply to Notification interval
43700
Time period First notification delay
180
Last notification
3000
Disabled no

Notification
user1
Name for the Icinga notification you are going to create

Imports

Users
user1
User groups Apply to Notification interval
3600 (inherited from “mail-service-notification”)
Time period First notification delay

I hope that I explained my needs correctly
Thank you in advance
