Thanks John.
I found and tested this:
if ( current_user_can('manage_options') ) {
add_action( 'load-edit.php', function() {
add_filter( 'views_edit-cptname', 'function_name_to_Call' );
});
}
It loads in content into that header above the table perfectly, i can load in ACF field values but i cannot get the form in.
I haven’t tried acf_form() yet
Maybe i’ll mess about with it first.
