You can use drilldown event callback function for add new series as your drilldown: http://api.highcharts.com/highcharts#chart.events.drilldown

drilldown: function(e) {
  var chart = this,
    drilldowns = chart.userOptions.drilldown.series,
    series = [];
  e.preventDefault();
  Highcharts.each(drilldowns, function(p, i) {
    if (p.id.includes(e.point.name)) {
      chart.addSingleSeriesAsDrilldown(e.point, p);
    }
  });
  chart.applyDrilldown();
}

You can use addSingleSeriesAsDrilldown(), method similar to: http://api.highcharts.com/highcharts#Chart.addSeriesAsDrilldown

But you can add multiple series as drilldown with this method.

Here you can see an example how it can work:
