Service Depencancy Grouping Question


I have successfully been able to setup service dependencies in nagios with an entry below in servicedependencies.cfg

define servicedependency{
hostgroup_name sun_ds
service_description ping
dependent_hostgroup_name sun_ds
dependent_service_description NFScheck
execution_failure_criteria w,c
notification_failure_criteria w,u,c

My question is would it be possible to create a group of services for dependent_service_description, that could avoid having to create a single entry for each dependent_service_description in the servicedependencies.cfg file?
