Simulated discounts

Hi.

Some background: In some cases I need to call a third-party service which sends entry/order/shipment level discounts (there are not related to any promotions in the system) and then I need to apply these values.

I reviewed RemoveDiscountsActivity and CalculateDiscountsActivity and did the following trick to apply form discount:

foreach (var orderForm in _cartHelper.Cart.OrderForms.ToArray())
{
    orderForm.Discounts.Add(new OrderFormDiscount
    {
        DiscountName = SimulatedDiscountName, // @SimulatedDiscount
        DiscountValue = discountValue
    });
}

But the same trick doesnt work for line item discounts. And for shipments discounts I didnt even try.

Maybe someone can help me with it or suggest the better solution.

Thanks.
