showing in Back Office total value of order without shipping

Hello.
Is there a free way so that opencart shows the total of an order without the shipping fees. Everything else should function as normal.

If i have an order with

100 $ for the products
25 $ shipping fee
125 $ total of the order.


In back-office

Home
Orders
where we have the columns (print-screen attached)
Order ID Customer Status Total Date Added Date Modified

the order from above to show only the 100 $ of the products in the column of total.


Or we can have the columns

total of products shipping fee total of order


And the dashbord on
Total Sales
to show the total of sales without the transport fee
