Including post fields inside MB Tabs

I tried adding the "tab" attribute to the post fields, but that doesn't seem to work:

add_filter( 'rwmb_frontend_post_title', function( $field ) {
    $field['type'] = 'text';
    $field['name'] = 'Name';
    $field['size'] = 60;
    $field['tab'] = 'basic';
    return $field;
} );

I'll have to resort to setting up dummy post meta to update post fields. But please let me know if there's a better way. Thanks!
