PL/SQL Formatting of AS/IS/RETURN

Is it possible to add formatting options to the AS, IS and RETURN keywords in FUNCTIONS/PROCEDURES/PACKAGES so that they can be configured either on the same line or after the definition line?

This option would allow this PL/SQL to be formatted like the following:

CREATE OR REPLACE PACKAGE BODY pkg_archive_process
AS
  gerror          NUMBER;
  gpackageversion NUMBER;

FUNCTION l_f_get_process_id (a_process_name VARCHAR2) 
  RETURN NUMBER
IS
  PRAGMA AUTONOMOUS_TRANSACTION;
  l_process_id NUMBER;
...

would become...

CREATE OR REPLACE PACKAGE BODY pkg_archive_process AS
  gerror          NUMBER;
  gpackageversion NUMBER;

FUNCTION l_f_get_process_id (a_process_name VARCHAR2) RETURN NUMBER IS
  PRAGMA AUTONOMOUS_TRANSACTION;
  l_process_id NUMBER;
...
