Global discounts configurable to be applied by the seller and not automatic.

We recently started using global discounts in our electronic products category, however handy automatically adds the discount to the ticket.

We would like to be able to have control and for the seller to be able to decide, based on our guidance, whether or not to apply the discount to the customer.

Something like the PROMOTIONS with prize section... which is the collaborator who decides in HANDY whether or not to apply the prize to the customer.
