Posting overpayments to specific GL

Hello Experts,

We have requirement to post any overpayments to the customer account to a specific GL account. So basically they can remain with the customer account but until and unless they are cleared by some receivables - they need to remain in a different GL bucket. E.g. If normal payment process debits the bank clearing and credits the A/R then we would like to debit the bank clearing and credits the Overpayment A/R. Once we post receivables on the account and after account maintenance is executed - then we would like to debit this overpayment A/R and credit the actual A/R. Is there any way this can be done? Any solution would be awesome. Thanks.

Regards,

A-jay.
