Is there any way to apply a global discount dynamically based on the customer group.
Eg. Customer A belongs to Group1 and defines global sales discount 10% when he logs in and add products to the cart.
Customer B belongs to Group2 and defines global sales discount 5% when he logs in and adds products to the cart.
Also this discount should be displayed everywhere cart/invoice/shipment.
I have checked several link but all are custom discount like Custom Discount
Would like to change sales discount on the fly based on customer logged in.
