Both in "Order discounts" and "Sales discounts" we need the possibility of to adding "Smart search" in "Sales discounts" and select a "Smart search" in Order discounts under "Excluded products". This way we can create a "Smart search" with all outlet products (outlet checkbox = true) and then exclude these products from the order discounts.
I hope this is possible in the next release.
Best regards.
