Dynamically update subtitle on Highcharts chart?

Is it possible to dynamically update the subtitle of a Highcharts chart?

In the docs, I can only see options relating to initial configuration options, not methods to update the chart.

In the update I’m doing, I’m also updating the data, and I’d like the highcharts update to be part of a smooth redraw if possible, rather than re-rendering the whole chart.

    subtitle: {
        text: 'The subtitle'
    }, ...
//how to update after initial config?




var chart = $('#container').highcharts();
$('#clickme').on('click', function() {
       chart.setTitle(null, { text: 'New subtitle '});
