Override Discount Price List in Kinetic

We have situations where we discount customers based on grade of material they are purchasing. So we have 3 discount price lists, AAA, AA, and A tied to a customer. We then want to select on the order line the discount price list appropriate to the grade of material being purchased.

In Classic, if you had 2 or more discount price lists tied to a customer, you could override the discount price list on an order line with another discount price list assigned to that customer. In Kinetic, if we try to override on the order line with another discount price list, it displays as options the price lists from the unit price, not the other discount price lists. They are set to type unit price list and not both

Anyone else using discount price lists in Kinetic trying to override with another discount price list?
