Yes. The key is to define a function cd() that, when called, also
sets PS1 in addition to performing the actual "cd". (This approach
can also be used for the Korn shell.)
I have adapted the following snippet for $ENV without testing:
PROMPT="$(whoami)@$(hostname -s):"
cd()
{
command cd "$@"
case ${PWD} in
"${HOME}"*) PS1="${PROMPT}~${PWD#${HOME}}\$ " ;;
*) PS1="${PROMPT}${PWD}\$ " ;;
esac
}
cd "${PWD}" # initialize prompt
