Sales invoice reconciliation

Good day, I make a bank receipt from a customer without choosing invoice, how can I reconcile this amount with a specific invoice

If you do not choose the invoice, Manager will allocate the receipt automatically to the unpaid sales invoice with the oldest due date. If more money is available, the allocation goes to the next oldest due date, and so forth. The only way to “reconcile” is to view the sales invoices and see where the receipt was allocated.

But if you want to know where the receipt was applied, why not just choose the invoice?
