Webcheck scenario step number in trigger message

[arr1val]

Greetings.
I have easy webscenario with multiple steps that check subdomains for code 200 and some required strings on page.

Trigger expression:

length(last(/example.com/web.test.error[WWW2check]))>0 and last(/example/web.test.fail[WWW2check])<>0

Trigger name:

{HOST.NAME} - failed: {ITEM.VALUE}

Also read https://support.zabbix.com/browse/ZBXNEXT-209 that STEP name unavailable.
Now i have:

Problem: example.com - failed: response code "502" did not match any of the required status codes "200"

Will be more usefull:

Problem: example.com - failed at step #: response code "502" did not match any of the required status codes "200"

Please advise how to do this.
