MT940 - BANK STATEMENT IMPORT: Is possible to sum different quantities contained in the same segment?

Some transactions or lines into the import file has an extra bank charge not included into the supplier invoice or open item, but the total payment includes this extra bank charge:

 

In case of the charge will be not included at the invoice, I need to find a solution to sum: Invoice + charges = Payment and achieve the match between the payment and the invoice with BSI process.

I am looking for a solution to match the invoice amount (or open item) with the payment amount because of both amounts are different due to the extra bank charges.

Any help or comment will be welcomed.

Thanks in advance.
