 '''Current Functionality (since 3.1.0):'''  One can add a CPT as a submenu
 of another CPT by setting the ''show_in_menu'' argument of the
 ''register_post_type()'' function as
 ''edit.php?post_type=CUSTOM_CPT_SLUG''.  The submenu is then added into
 the administration menu by way of the ''_add_post_type_submenus()''
 function.  When this occurs, the submenu CPT's are displayed in the order
 the CPTs were registered.

 '''Problem:'''  The current coding prohibits the ordering of CPT submenu
 items per the programmer's desires in the event CPT registration is unable
 to be controlled or in the event other submenu pages are added via the
 ''add_submenu_page()'' method.  This occurs because the call to
 [https://developer.wordpress.org/reference/functions/add_submenu_page/#source
 add_submenu_page()] by
 [https://developer.wordpress.org/reference/functions/_add_post_type_submenus/#source
 _add_post_type_submenus()] only passes 5 arguments.  (The sixth omitted
 argument is what handles menu positioning.)

 '''Solution:'''  The ''menu_position'' argument passed to the
 ''register_post_type()'' function already exists, and defines a CPT's
 positioning within a menu.  The solution is to incorporate this argument
 into the core by modifying line 2079 of
 [https://core.trac.wordpress.org/browser/tags/6.2/src/wp-
 includes/post.php#L2079 wp-includes/post.php] as follows:
 {{{
 add_submenu_page(
    $ptype_obj->show_in_menu,
    $ptype_obj->labels->name,
    $ptype_obj->labels->all_items,
    $ptype_obj->cap->edit_posts,
    "edit.php?post_type=$ptype",
    is_set($ptype_obj->menu_position) ? $ptype_obj->menu_position : NULL
 );
 }}}
