How to set value of Excel cell by name instead of using coordinates with EPPlus?

Question

I am able to set cell values using EPPlus:

var template = new FileInfo(Server.MapPath("~/App_Data/my_template.xlsx"));
var pck = new ExcelPackage(template);
var ws = pck.Workbook.Worksheets.First();
ws.Cells[15, 4].Value = 66; 
ws.Cells["B1"].Value = 55;

Instead of addressing the target cell by its coordinates I would like to use a named cell/variable "profits".

ws.Range("profits").Value = 66;

However, EPPlus does not support ws.Range(...).

=> Is it nevertheless possible to do so? How would I write an extension method that provides the wanted functionality?

Is there a way to get 'named' cells using EPPlus?

It is also possible to set the values for a named range:

var ws = pck.Workbook.Worksheets.First();
using (var namedRange = pck.Workbook.Names["MyNamedRange"])
      {
        for (int rowIndex = namedRange.Start.Row; rowIndex <= namedRange.End.Row; rowIndex++)
        {
          for (int columnIndex = namedRange.Start.Column; columnIndex <= namedRange.End.Column; columnIndex++)
          {
            ws.Cells[rowIndex, columnIndex].Value = 66;
          }
        }
      }
