Changing users after connecting to remote machine

[J. David Boyd]

Many of our production machines are set up in a way that we have to:

1. Log in as ourselves
2. 'su -' to the user to do work as
3. exit
4. exit


I've perused the docs, and don't see any way to do this.

Is it possible in Tramp?  I hope?  I'd love to be able to connect
through my local emacs, and edit files out there on our system.

Thanks,
