Yes, I've tried that, and it can work, I think, if you want to start numbering with the first cell of any row. But I would like to start with something other than the first cell of any given row, like the second or third, and so on, and after that I am supposing there would be a way to stop the numbering at an end point, such as 1-20, and any cells after that point would be left without numbering.
