I need a "tax" column in invoices

[kkirk]

I live near the border of 2 states and our tax rates vary depending on what state we did our work in. It would be a huge time saver if I could have a column that listed the tax rate along with the other columns (item, price, qty ,total). Right now if I want to know the tax rate of each item I add to the invoice, I have to click on each item. It would be a huge time saver to just have it listed in a column. Is this possible? I'm not seeing it anywhere but maybe I'm missing it.
