How to set tag on discovered trigger based on match discovery value vs macros

[GIL]

Hi 2 all. To properly summ SLA i need tags on services triggers based on Windows Template.
I have build some macros in template with names of services that are really critical for server to work:
{$SERVICES.CRITICAL} = ^(?:Winmgmt|W32Time|RpcSs|NTDS|Netlogon|MSTDC|Lanm anServer|Kdc|IsmServ|DNS|DHCPServer|DFSR|Dfs|ADWS) $
Now i need somehow assign tag or tag vs value based on discovered service name match macros expression.
How to do that?

service.discvoery item returns all the needed info..
edit the item prototype and set a tag (whatever name you like) and value as {#SERVICE.NAME}
