Make Servicegroups available to assign to Contactgroups

I would like to suggest that the service groups can also be assigned to contact groups.
Currently we have here only the following conditions:

Service groups are the result of a configuration. They are not attributes of services that can be used for configuration. If you need to have the services of a service group in a contact group you need to create rules with the same conditions. Predefined conditions may help here.

Another suggestion: Use service labels to assign service groups and contact groups. That makes it easier if you need to group a diverse set of services.

Okay … then it will be a good Idea to call a Servicegroup and have the possibility to set a Servicelabel to this group.

You have to think the other way around. Use the ruleset “Service Label” to label services and then use the label to assign them to a service group and a contact group.
