Global, template and host defined lists

Hy!

I have a suggestion for new feature.

I'm using Zabbix to monitor DNS changes (for high availability environments), and my DNS servers is a pool with X members.

I need to query DNS A in each server with this key

net.dns.record[<DNS server IP>,<DNS record>,A,20,2,udp]

I'm created one item for each DNS server IP X and DNS record, maintenance this is terrible =(

My suggestion is: On frontend, create lists, with identifiers, example:

DNS_SERVERS_LIST [10.0.0.1, 172.16.0.1, 192.168.0.1]

And when user define this list on discovery rule, create one itemkey per index on DNS_SERVERS_LIST, the result is:

net.dns.record[10.0.0.1,mydns.corp.internal,A,20,2,udp]
net.dns.record[172.16.0.1,mydns.corp.internal,A,20,2,udp]
net.dns.record[192.168.0.1,mydns.corp.internal,A,20,2,udp]

And this lists has the same behavior of macros

Global --> Template --> Hosts

Thanks!
