Possible to specify the tmp username from the outside of jupyterhub?

Hi, I am wondering whether it is possible to specify the name of the tmp user when starting a new notebook server in tmpauthenticator, something like:

`https://jupyterhub.example.com:8000?name=new_username`

My simple goal is to have a web page that will be able to redirect to the jupyterhub to start a server with sending a single piece of info to each notebook server. Any hints would be highly appreciated.

Thanks!
