How to make one consistent hashing for two http routes?

Networking

Hi there. I have an app that uses two ports. And I need consistent hashing by http header between there instances with both ports. For now it looks like it is separated. For example I send request to sampleadress:4242/users with header sampleHeader:x and I need second request sampleadress:8080/something2 with header sampleHeader:x get routed to the same instance.
With my current setup consistent hashing is working but the buckets with hashes are separated for 4242 and 8080 ports. Below is my configuration. I hope someone could help.

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: {{ template "component.name" . }}
  labels:
    name: {{ template "component.name" . }}
spec:
  exportTo:
{{- range .Values.component.infrastructure.istio.ingressGateway.exportTo }}
    - {{ . }}
{{- end                                                                  }}
  gateways:
{{- if .Values.component.infrastructure.istio.ingressGateway.name        }}
    - {{ .Values.component.infrastructure.istio.ingressGateway.name      }}
{{- end                                                                  }}
    - mesh
  hosts:
    - {{ printf "%s.%s.%s" $.Chart.Name $.Release.Namespace "svc.cluster.local"  | lower }}
{{- range .Values.component.infrastructure.istio.ingressGateway.hosts    }}
    - {{ . }}
{{- end                                                                  }}
  http:
    - name: {{ template "component.name" . }}-admin-routes
      match:
        - uri:
            prefix: "/users"
        - uri:
            prefix: "/errors"
      route:
        - destination:
            host: {{ printf "%s.%s.%s" .Chart.Name .Release.Namespace "svc.cluster.local"  | lower }}
            port:
              number: 4242
    - name: {{ template "component.name" . }}-routes
      route:
        - destination:
            host: {{ printf "%s.%s.%s" .Chart.Name .Release.Namespace "svc.cluster.local"  | lower }}
            port:
              number:8080

Hi, did you solve this problem already? I have the same requirements.
