possible to use a part of the string (of key value) in trigger name,

for example :

I'm using zabbix_sender to forward the SNMP traps to Zabbix server, for example:
/usr/local/bin/zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k GeneralSnmpKey -o msg="test12 failed with error1 and error2"

And I want to set the alert message only the text "test12 failed" - alert will be on "test12 failed on <host>"

I can present all the value: "test12 failed with error1 and error2" but no way to split it into variables.

Thanks
