That is exactly what I want!! Thank you!
Added bonus: it seems I can use this with any other mode.

I've updated the code:
https://github.com/sri/dotfiles/commit/3b2e42f488393dfc0f7fa91887877af5b195a20c

And I'm invoking it like so:

(add-hook 'org-mode-hook
          (lambda ()
            (my-org-create-dynamic-link
             "\\([[:alpha:]]\\{2,5\\}-[[:digit:]]+\\)"
             "https://www.some-ticket-system/%s")))
