Resolving overpaid status

For resolving the overpaid status, according to the manual, i have to allocate to the right invoice,

but (with a lot of invoices) it’s hard to find the right invoice to allocate with only the invoice-number to select. Is there another way to find the right invoice?

Maybe by adding the amount to the invoice-number select option would help a lot.

Actually you either allocate to the right invoice or don’t allocate to any invoice at all (so Manager will automatically find the next unpaid invoice. This way you will not end up with overpaid invoice.

The most that weren’t right allocated where payments of multiple invoices from one customers in one payment. I removed them and allocated them one by one.
