In addition to the work you have already done, we would like to add buttons to each row of the spreadsheet. We would like the buttons to add/subtract rows. Each row would have a "+" and a "-" button to the right of the last column (currently the "% Towards Goal" column). When the user selects the "+" button, a new row is added directly below. When the user selects the "-" button, the user removes the current row. See attached files.
