Service Annotation

When creating a deployment via something like:

rancher kubectl create -f ./some-deployment.yaml

Rancher automatically creates the services required by the deployment. Is there a way to provide annotations for the service in the deployment file? Specifically I wish to have

external-dns.alpha.kubernetes.io/hostname: some.host.name

annotation on the service, without having to adjust the service manually or through tooling.

Thanks
