Using Autolockbox without invoice information

Hi All,

    Is it possible to use Autolockbox wherein the invoice information is not available- customer deposits the amount in the bank without specifying the invoice which he is paying for . So in effect we would need Autolock box to process bank files using the customer number and then Post quick cash would apply the receipt using the Auto cash rules.

Is this possible?

Thanks in advance.
