In Odoo 17, I created a single batch transfer with multiple delivery orders of different sales orders with the combination of the same and different products. In that, I need a consolidated picking slip to know how many items I need to pick. 

For eg: 

The above screenshot is the reference. If I print the picking slip for the above batch transfer, it shows separate line items for the same product. But I need, if the Qweb report should contain 

Products  ​ ​ ​ ​ ​Demand ​ ​UOM

Annai Dhall ​ ​ ​ ​15   ​ ​ ​Units
BULLET RICE NAGA  ​ ​ ​25   ​ ​ ​26Kg Bag

ANNAI URAD DHALL (2Kg) ​  1   ​ ​ ​Units

ANNAI URAD DHALL (3Kg) ​  1   ​ ​ ​Units

Fragrance Stick   ​ ​ ​50   ​ ​ ​Units

For this how to customize the qweb reports?
