I need to customize the aria-label for legends in highcharts with a pie chart. Right now with the help of labelFormatter(https://api.highcharts.com/highcharts/legend.labelFormatter), I have created custom label text but aria-label for them is generated by default WRT to series names.

In below example, point name is water heating but I have created a custom label as €29 water heating. And, the problem with this is aria-label text generated by highchart for this is water heating.

So, want to know if there is any way to customize aria-label text for legends.
