James,

It was actually quite easy, since the column is there purely for reference (no need to filter etc.). Perhaps the code is useful for someone else! 🙂

function build_listing_column_head( $columns, $post_type = 'listing' ) {

	if( ! is_admin() ) {
		return;
	}

	if( $post_type == get_post_type() ) {
		$columns['relation'] = esc_html__( 'Relation', 'lystr' );
	}

	return $columns;

}

add_action( 'manage_listing_posts_columns', 'build_listing_column_head', 10, 2 );

function build_listing_column_content( $column, $post_id ) {

	global $post;

	if( ! is_admin() || 'relation' !== $column ) {
		return;
	}

	$relation = get_field( 'relationship', $post->ID, false );

	if( ! empty( $relation ) ) {

		$id = implode( ',', $relation );
		$title = get_the_title( $id );
		echo $title;

	}

}

Thanks for your help! 🙂
