Is it possible to execute a command after the start of the "ddev-router" (traefik)?

Question

It's possible to execute a command on the host after the start of a project with the file ".ddev/config.yaml" of the project like this:

hooks:
  post-start:
  - exec-host: the-command

But, can we do the same for the "ddev-router" ?

I tried to find the traefik.yaml to add the hooks, but I think it will not works...
