Apply downloaded transactions directly to A/R or A/P manually

A user has suggested it would be more efficient to be able to apply downloaded transactions in the register against A/R or A/P, for example a deposit could be a payment against a customer invoice.  This would avoid the "undeposited funds" and "payments in transit" accounts altogether, presumably.

Although this would be a major change, it might be worth considering at some point in the future.
