How to Write to Excel Cell index

In the Excel activity Write Value you the Range object is default at “A1”

How can I adress the cell index instead - like the below VBA code:

Range(“A1”) = 1

Cells(1, 1) = 1
Range(Cells(1, 1), Cells(1, 1)) = 1

Do UiPath Excel activities support R1C1 style notation or only the “A1” style notation? I think that is the root of this question, and is a question I’d also like to know the answer to.
