Yes, there are many ways to do this:

(add-hook 'dired-after-readin-hook 'rename-uniquely)

(add-hook 'compilation-mode-hook 'rename-uniquely)

or better

(setq compilation-buffer-name-function
      (lambda (mode-name)
        (generate-new-buffer-name
         (concat "*" (downcase mode-name) "*"))))
