Router Host regex variable re-use

Traefik Traefik v2
1

Is it possible to use the variable in the regex between routers and services in Traefik 2.0? I saw a similar question for Traefix 1.x, but I didn't know if the feature was added.

  routers:
    test:
      entryPoints:
        - "http"
        - "https" 
      rule: "Host(`test.{domain:(app|dev)}.blah.com`) || Host(`test.{domain:(app|dev)}.blah.com`)"
      service: test
  services:
    test:
      loadBalancer:
        servers:
          - url: "https://test.$domain.blah.com:81/"

Hello,

I recommend to use the redirectRegex middleware: https://docs.traefik.io/v2.0/middlewares/redirectregex/

I implemented the RedirectRegex. It will only work on http commands, but not on https? Is it not possible to redirect on https? Below is my config

http:
  middlewares:
    https-redirect:
      redirectScheme:
        scheme: https
    dfp-redirect:
      redirectRegex:
        regex: "^http://(.*).company.com"
        replacement: "http://${1}.company.com:81"
    dfpssl-redirect:
      redirectRegex:
        regex: "^https://(.*).company.com"
        replacement: "https://${1}.company.com:444"
  routers:
    test:
      entryPoints:
        - "http"
        - "https" 
      rule: "HostRegexp(`test.{domain:(app|dev)}.company.com`)"
      middlewares:
        - dfpssl-redirect
        - dfp-redirect
      service: anything
  services:
    anything:
      loadBalancer:
        servers:
        - url: "http://fake/"

In the v2 the TLS is on the router https://docs.traefik.io/v2.0/routing/routers/#tls
