How can I manage formulas in subtotals?

[iRumba]

When I use tag <<sum>>, i have subtotals() in result. But i want sum()

Here is the code that manages the formulas in the tag <<group>>

ClosedXML.Report/ClosedXML.Report/Excel/Subtotal.cs

Line 289 in 230d148

summRow.Cell(summ.Column).FormulaA1 = $"Subtotal({summ.FuncNum},{funcRngAddr.ToStringRelative()})";

Now there is no way to change the formula, but you can contribute to the project and offer your PR.
