Currently, we have some available smart values for the "Affected services" field. These available smart values do not include the "Stakeholders" field from a service.

It would be nice to have a "Stakeholders" smart value, so we can interact with those users (add them to the "Request participants" field, for example) using automation actions.

Workaround (Only on Premium/Enterprise):
It's possible to use the "Lookup objects" action to search for the services from the "Affected services" field.

Name in ({{"Affected services".Name.asJsonString}})

Once we get the response from the above query, we can access the "Stakeholders" values using the following smart value:

{{lookupObjects."Stakeholders"}}
