Is it possible to reference columns/rows by name?

[jzhang1]

Instead of referencing columns/rows by index like $1, is it possible to give them names and reference them in formulas? The reason for this is because if I reorder columns/rows, the formulas would have to all be updated. It also makes the formulas difficult to read to reference everything by index.

Formulas would be substantially easier to read if they looked like $total = ($price * $quantity * !taxrate)
