Requestor -> Uses -> Service Y

Example:

5 Requestors are interested in Finance application (service)

Service has an incident, Requestors need to be notified of incident

Now without adding all 5 manually (example only as real no.s of requestors to services is 000's) can I email notify only requestors interested in the specific service?

One option:

Requestors have an email address attribute, can a service have an email attribute (similar to a distribution list) and when the requestor is assigned to the service their email address is automatically added (or deleted when no longer required) to the Service email?

Thanks
