ls-lisp emulates the Unix and GNU 'ls'.  So I will generally oppose to
introducing any option into it that cannot be had with an external
'ls' program, as long as the latter is the main method of getting a
Dired buffer.  (If Emacs ever decides that ls-lisp becomes the main
method, and will use it by default on all supported platforms, this
objection will no longer be valid, of course.)

An alternative to what you want would be a Dired-level feature, which
then will be available also to those who don't use ls-lisp.
