A good UI to select the desired behavior before the command invocation
is to use a prefix argument.  A comment in `dired-shell-stuff-it' says:

  ;; Might be redefined for smarter things and could then use RAW-ARG
  ;; (coming from interactive P and currently ignored) to decide what to do.
  ;; Smart would be a way to access basename or extension of file names.

I don't know how it was intended to be implemented a smart way, but
maybe the same could be used to specify how to run dired async commands?
