Not as visually appealing, but you can separate commands using the
semi-colon. So when you hit C-p and want to add another command just
type a ; first and then continue with the next command.

Another way to do it is using zsh's history expansion[1].
!! recalls the previous command so you can type:

    % !! ; <next command line to execute>

I know this is not what you asked for, but I hope this helps a bit.

[1] I don't want to rant because I'm really fond of history expn, but
you should look into them further at:
