Ingress Controller Allow dynamic port in Access-Control-Allow-Origin

I need to specify random port for nginx.ingress.kubernetes.io/cors-allow-origin

My configuration is:

  annotations:
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, POST, PUT, DELETE, OPTIONS"
    nginx.ingress.kubernetes.io/cors-allow-credentials: "true"
    nginx.ingress.kubernetes.io/cors-max-age: 3600
    nginx.ingress.kubernetes.io/cors-allow-headers: "Cache-Control,Content-Type,Authorization,Origin,Accept"
    nginx.ingress.kubernetes.io/configuration-snippet: |
      if ($http_origin ~* (^(http://localhost(:\d+)?)$|^(https://(.+\.)?mydomain.com)$)) {
      more_set_headers "Access-Control-Allow-Origin: $http_origin";
      }

But Access-Control-Allow-Origin value overrided for requests and it shows ‘*’

btw: nginx.ingress.kubernetes.io/cors-allow-origin by default eq ‘*’ ( ingress-nginx/annotations.md at main · kubernetes/ingress-nginx · GitHub)

Can I set allowed origin using Access-Control-Allow-Origin ?
