Apex Charts Custom tooltip: How to alter alignment of seriesName in tooltip?

[githubHemanth]

I am trying to get the series name aligned to center, beside the color in the tooltip, as the value in my tooltip has a couple of lines of data. The series name is by default aligned bottom-left corner.
How to align series name to center beside the color?
Please view the attached image for a clear understanding of my question.

Ignore series data values in the code below

tooltip: {
     y: {
    formatter: function (value, { seriesIndex, dataPointIndex, w }) {
      var label = w.config.series[seriesIndex].labels[dataPointIndex];
      var labelTooltip = label.replace(/\n/g, '<br>');
      return labelTooltip;
    }
 }
}, 
xaxis: {
categories: ['<0 Days', '0-30 Days', '31-60 Days', '61-90 Days', '91-180 Days', '>180 Days'],
labels: { show: true }},

series: [
{ name: 'Low (0 - 25%)', data: [rep_estval_low[1], 200000, 1000000, 500000, 400000, 600000], labels: rep_label_low.slice(1, 7) },
{ name: 'Medium (50%)', data: [600000, 120000, 650000, 750000, 110000, 900000], labels: rep_label_med.slice(1, 7) },
{ name: 'High (75 - 100%)', data: [rep_estval_high[1], 900000, 115000, 350000, 650000, 120000], labels: rep_label_high.slice(1, 7) }
],
