[20.10][Feature] Sending only one identical notification for multiple hosts

[Shadok]

Hello,

Running centreon 20.10 on Ubuntu, i am wondering if there is a way to send only one notification for multiple hosts when the issue is the same ?

I have an isilon nas consisting on multiple nodes.
Each one are monitored since they can have hardware issues and some can be down.

But, hardware issues excepted, some warning or errors can be common to all the hosts.
Example : the policy warning, if i get one, i will get the same one on all the hosts and i'd like to have only one notification since it's one fix to do for all the nodes.
The main issue is that i don't have a master i could monitor so only one host could return this kind of warning.

Is there a way to centralize notifications for a group of hosts if the situation is the same ?

Thanks.

For now, i only check the policy errors on one node, it works as intended, but that's not really optimal.
If there is no other way, i'll keep this solution, it's better than nothing.
