Is there a way to expand the clickable region of a point in Highcharts so that a click can be registered whenever the point is 'active'?

Forgive me for the slightly convoluted question, but let me provide further clarification.

In Highcharts.js, when you move your mouse into the area of a point on a line chart, it hovers over the point and loads the tooltip. I currently have some click event operations implemented successfully, but I am looking to adjust them so that users can 'click' the points even when the mouse is not directly over them, but within range to hover over the point.

What would be the best approach to achieve this functionality?

chart: {
    events: {
        click: function (event) {
            var infoLabel = this.renderer.label(
                    'Clicked at x-coordinate: ' + Highcharts.numberFormat(event.xAxis[0].value, 2) + ', y-coordinate: ' + Highcharts.numberFormat(event.yAxis[0].value, 2),
                    event.xAxis[0].axis.toPixels(event.xAxis[0].value),
                    event.yAxis[0].axis.toPixels(event.yAxis[0].value)
                )
                    .attr({
                        fill: Highcharts.getOptions().colors[0],
                        padding: 10,
                        r: 5,
                        zIndex: 8
                    })
                    .css({
                        color: '#FFFFFF'
                    })
                    .add();

            setTimeout(function () {
                infoLabel.fadeOut();
            }, 1000);
        }
    }
}
