All right. Is that location a certain symbol's definition, or just some 
special location that can only be found by a grep search?

But you still use project-find-regexp for its "normal" purpose, too, 
right? That is, finding all occurrences of a certain regexp. Maybe to 
rename all occurrences of a symbol, etc.

To only change its behavior in specific situations, you can add a new 
command to your init script and bind it to a key. The code can look like:

(defun project-find-regexp-and-jump ()
   (interactive)
   ;; Or use a particular function name here directly.
   (let ((xref-show-xrefs-function xref-show-definitions-function))
     (call-interactively #'project-find-regexp)))

Other suggestions welcome, of course.
