有没有一种方法可以让我们在istio虚拟服务中为单个上下文路径指定两个服务？

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: my-service
spec:
  hosts:
    - "*"
  http:
    - match:
        - uri:
            prefix: /servicepath
      route:
        - destination:
            host: service-a
            subset: v1
          weight: 90
        - destination:
            host: service-b
            subset: v1
          weight: 10
