So, if I understand you correctly, in the backend of hikashop in the listing of orders, you would like the display the total weight as well as the total volume of each order. Is that correct ?
If so, it's not possible by default. It would be possible by editing the file listing of the view order of the backend via the menu Display->Views to add those two columns and calculate this total weight and total volume information. But you need to know PHP to do that or we could do it for you for a small fee.
