On Zabbix it's possible to use {TRIGGER.ID} macro on trigger tags. It's not explicit on documentation at this moment.

Please add on specific documentation section the possibility to use {TRIGGER.ID} tags among with the others already there: 

The following macros may be used in trigger tags:

• *

  {ITEM.VALUE}

  , {ITEM.LASTVALUE}, {HOST.HOST}, {HOST.NAME}, {HOST.CONN}, {HOST.DNS}, {HOST.IP}, {HOST.PORT} and {HOST.ID} macros can be used to populate the tag name or tag value*
