Multiple Service objects for Envoy

We use Envoy Gateway in GKE. By default, GKE exposes Services to the public network. For private networks, a specific annotation (`networking.gke.io/load-balancer-type: "Internal"`) must be added to a Service object.

To use the same Envoy instance for both public and private networks, we need to create an additional Service object (with the annotation) for the private network manually.

Is there a way to configure multiple Service resources for Envoy out of the box?
