Zabbix Server : 5.2.6

OS :  8.3.2011

Steps to reproduce:

1. Create an item Zabbix Internal for create one item by IP in host
2. Create another item Simple Check (icmpping or icmppingsec) with the value of previous created item like trigger macro "{HOST.KEY.VALUE}" but in item.

Result:
It doesn't work because I can't use the item value in other items.

Expected:
I want make a discovery (Zabbix Internal) for create 3 items :

1. Public IP
2. VPN IP
3. Backup IP

With theses items, I would make 3 items where they names contains the IP and different severity.

I did not find how to do it but there may be a solution.

Thanks advance for your time.
