Price component for 'internal' use

Hello,
I added a fee price component to my products (i.e. 10$) which adds a relative amount (i.e. 1$) to each line-item. The unit prices and total prices of that line-items on the checkout review pane appear correctly as a total (i.e. 11$). However, in the footer there is the Order:Total handler which prints:

Subtotal: 10$
Fee: 1$
Order Total: 11$

instead of only:

Order Total 11$

or with VAT enabled:

Subtotal: 11$
VAT: 0.50$
Order Total: 11.50$

The customer should neve see the fees. They are just for internal use (it's about a little marketplace and the fee is what the merchant has to pay to the shop owner - not interesting for the customers).

So the question is if it's possible that "Subtotal" is always calculated on the unit-price instead only of the base-price? Or equivalent: calculated on base_price component + all components with attribute "included = TRUE"?

In general I miss a function, that just returns the formatted/raw price of a line-item including all pricing rules and components. Or did I overlook it?

I'm not sure if it would help much if I wrote my own views area handler for that as the order summary also will be printed out in the order e-mail (and maybe additional places?).

Here's my $line-item->commerce_unit_price from the above example:

Array
(
    [amount] => 1100
    [currency_code] => USD
    [data] => Array
        (
            [components] => Array
                (
                    [0] => Array
                        (
                            [name] => base_price
                            [price] => Array
                                (
                                    [amount] => 1000
                                    [currency_code] => USD
                                    [data] => Array
                                        (
                                        )
                                )
                            [included] => 1
                        )
                    [1] => Array
                        (
                            [name] => fee
                            [price] => Array
                                (
                                    [amount] => 100
                                    [currency_code] => USD
                                    [data] => Array
                                        (
                                        )
                                )
                            [included] => 1
                        )
                )
        )
)
