How to get host LOCATION in alert messages?

How to get host LOCATION in alert messages? I saw documentations about "Macros supported by location" and try to use macros {INVENTORY.LOCATION<1-9>} in Trigger-based notifications. But macro isn't resolved in Trigger name.
By example in "Template ICMP Ping" trigger:

{HOST.NAME} is unavailable by ICMP location {INVENTORY.LOCATION1}

I get message:

PROBLEM: n622.mydomain.local is unavailable by ICMP location {INVENTORY.LOCATION1}
