I need help with Odoo POS.

I want the untaxed amount to be visible to the cashier before proceeding with the payment. How can I achieve this?

i cant upload a photo but this is an example 


product(1) = before tax is (32)
product(2) = before tax is (21)

taxes ​ ​ ​ ​7.95
total ​ ​ ​ ​ ​60.95



in the total i want the price appears without the tax so it should be 53.
but when proceeds to payments it shows the taxes
