Multiple $args in array in 'genesis_grid_loop_args' filter?

Hello, I’m trying to put more than one $arg in the genesis_grid_loop_args filter but I’m not coming up with the correct syntax.

I’m trying to do something like the following (note: the following does not work):

function page_grid_args( $args, $query ) {

    if( is_post_type_archive( 'press' ))
        $args = array(
          'features_on_front' = 0,
          'teasers_on_front' = 4,
          'teaser_columns' = 4)
      return $args;
}
add_filter( 'genesis_grid_loop_args', 'page_grid_args', 10, 2 );

I came up with the following work-around, which does work, but I’m not sure its “proper” code syntax:

function page_grid_args( $args, $query ) {

    if( is_post_type_archive( 'press' ))
        $args['features_on_front'] = 0;
    if( is_post_type_archive( 'press' ))
        $args['teaser_columns'] = 3;
    if( is_post_type_archive( 'press' ))
        $args['teasers_on_front'] = 9;
    if( is_post_type_archive( 'press' ))
        $args['features_on_front'] = 1;
    return $args;
}
add_filter( 'genesis_grid_loop_args', 'page_grid_args', 10, 2 );

Like I mentioned, this works but it seems pretty clunky, codewise, so I’m wondering if someone has a way to put the $args in an array within a single if statement.
