Istio - way to add prefix to route/destination?

Currently have Istio deployed to handle the ingress to my applications. Running into an issue where one app needs to be reachable via a certain URL such as "http://gateway/webapp1" and I need it to route internally to: server-name1:8080/some/odd/name/path

The current match statement I have is:

  - match:
    - uri:
      prefix: /webapp1
  route:
    - destination:
        host: server-name1
        port:
          number: 8080

I am unable to figure out how to expand on the destination route to tell it to hit a different endpoint that just server-name1:8080. Is there a simple way to add a prefix to the underlying route/destination? Thank you.

You can use the HTTP rewrite with the virtual service before sending traffic further

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: ratings-route
spec:
  hosts:
  - ratings.prod.svc.cluster.local
  http:
  - match:
    - uri:
        prefix: /webapp1
    rewrite:
      uri: /gateway/webapp1
    route:
    - destination:
        host: server-name1
        port:
          number: 8080
