Supplier balances - total for a period

This question is about the menu Purchases -> Supplier and Purchasing Reports -> Supplier Balances. My aim is to see the value of the transaction with a given supplier during a given period. When I request this report, it shows the initial balance, all the transactions and the final balance.

The final balance is the sum of the initial balance and all the transactions.

For a given period I am not so much interested in what the inital balance was, but much more what the transactions were. When I want to know just the value of the transactions, I have to substract the initial balance amount from the final balance amount.

Of course it can be done, but it is an additional action.

Is it designed this way, or am I doing something wrong?
