Kubernetes Ingress with Multiple Istio Gateway Controllers

Hi Team,

I’d like to use Kubernetes Ingress with Istio Gateway Controller. My clusters are hosted in AWS and I have multi-gateway-controller deployment. Each of them terminates TLS on ELB.
Is there a way to set label/additional annotation to Ingress to differentiate between gateway-controllers?

Thanks,
Sergii
