You should be able to change that to

  export PS1="$(tty)$"

which would set your prompt to the full path, something like

  /dev/tty1$

You could trim off the leading "/dev/" with

  export PS1="$(tty | sed 's#^/dev/##')$"

which would reduce it to just

  tty1$

This does merely assign it once when it's evaluated in your .bashrc,
so if you use something like reptyr(1) to move your shell to another
terminal, it won't update so you'd have to re-source your .bashrc
again.  Not a big deal and not something your average user is apt to
encounter, but still something to keep in mind.
