How to make a complex trigger (from several systems) in Zabbix?

Question

Zabbix

Colleagues, help with advice.
Is it possible to do something like a complex trigger or a complex item in Zabbix, in which several systems will participate. I want to do this for the compactness of displaying elements in the Dashboard.
Example: There are two routers for Internet access. I want to push one trigger into Dashboard - "Access to the Internet". If at least one router pings 8.8.8.8, then the trigger is green and does not send notifications that one of the routers has fallen off.
Maybe this is done through something else, in general, I need help, a hint =)
