I just discovered the existance of custom object variables which fulfill my
needs. I define warn/crit thresholds in default service definition and
modify them in local service definition if needed. Thus this became a
non-issue for me. (and just now when I already got familiar with Nagios
source code:)

Thanks for your hints/help anyway!

Best regards,
Bostjan
