I've encountered an issue where the total amount of some invoices do not match a predetermined amount due to rounding for each line item.  For example, in my screenshot below, suppose I want to bill for 1 hour at $72.25 per hour. But if it's split into two half-hour items, then the total is off by one cent.

Is there a way to create an invoice where the subtotal is not affected by rounding line items?
