Hi,
the solution I have done here at our nagios-system is this:
Every check has its own hostgroup, a definition looks like this:

define hostgroup{
        hostgroup_name          mysql-check
        register                0
        }

define service{
        use                             service-template
        hostgroup_name                  mysql-check
        service_description             MySQL Status
        check_command                   check_mysql
        }

The register 0 hides the group on the webinterface.

Now I add a host with a mysql database simply to this group, that can be done 
per host:

define host{
        use                     hosts-template
        host_name               important-server
        hostgroups              mysql-check
        }

Is this something you're looking for?
