Yes, with zsh that's also automatic.

Do any of you know of a way to get a number as the first cell(s)

I think that could be convenient when using braille.
There is probably a way in bash, like echoing $? at the beginning of the
prompt. However, mksh does that automatically. I think zsh does as well.
