You could put the following simple command in your initfile

   (defun align-repeat (start end regexp)
   "repeatedly align using a regexp as the field separator.
   Works on the current region"
     (interactive "r\nsAlign regexp: ")
     (if (equal start end)
        (message "no region !"))
     (align-regexp start end 
          (concat "\\(\\s-*\\)" regexp) 1 align-default-spacing t))
   
Then select your text, and type M-x align-repeat RET , RET
