Please add a way to edit the Owner statements

I've checked and OR PM is not configured (and cant be it seems) to calculate some items that I need to include in my monthly owner statements (i.e., calculating credit card fees & charging owner for these based on the gross rental amount, then deducting that from the commission calculation, so owners are not paying a commission on the credit card fees) . Since making the edits before the statement is generated is not possible, could you make the final generated statement editable so I can make the changes manually and change the figures. That would be extremely helpful.
