We would love to see functionality improvement where you can Edit Cell value to be equal another cell or formula calculating value from 2 cells or an option to calculate ROW to be driven from another row by right clicking on ROW and calculate, also add option to calculate cell itself by right clicking cell and ability to reference another cell/row.
Example case use would be to calculate bill of material in the table where for every vault we would need 20 bolts in which case we could create a calculate function in model builder not only calculating columns but also rows/cells by defining the row/column position.
