Two additional fields?

Is it possible to add two additional fields? In the first field, it should be possible to enter the amount the customer has already paid, and in the last field, the remaining amount due.

I too encounter such issues where customers do partial payments. 🙁 Without any fields to record partial payments unto the invoice, monitoring such payments have to be taken offline in another spreadsheet.
