Is it possible to ssh 2 levels deep in tmux (tmuxinator) init script?

Question

In order to reach the box I want to be ssh'd into, I need to go through an intermediary box. Assuming my keys are configured so I don't need to type passwords, is it possible to do something like this?

windows:
  - "innerbox": ssh proxybox; ssh innerbox

This syntax doesn't work. I get this output:

andersonbd1@localhost:~$ ssh proxybox; ssh innerbox
[andersonbd1@proxybox ~]$ 

It gets me into the first box, but not the second. If this is not possible in tmuxinator, but is possible in plain tmux, I'd appreciate that answer as well.
