I am using Odoo 12 Enterprise Edition.

When my Receiving Manager prints the Receipts due to be received, he can scan the Receipt barcode to open it and can scan the product barcode either on the product or the paperwork to receive products.

To complete the transfer, he either has to click the VALIDATE button on the handheld with his finger, or grab the separate barcode sheet of COMMANDS FOR INVENTORY.

Since he already has the Receipt paper in one hand and the scanner in another hand, he needs to put down the paperwork to use his finger to to get the separate sheet.

Can the VALIDATE barcode be printed at the bottom of the Receipt so he can just scan the paperwork he is already holding? 

Can this be done for Internal Transfer and Delivery paperwork (Picking Operations) also?
