[Observium] Alerting system: multiple associations

Hey guys,

I have the following alert checker:

As you can see, the checker is applied only to server devices but I'd like to extend that to storage devices.

Is there a simple way to modify the device match rule in something like "type equals (server or storage)"?

I tried searching any suggestion on the wiki and on the mail archive, but I didn't find anything.

Thanks for any hints,

Stefano
