E9.2 Basket pricing - apply only one discount


I'm trying to set up basket pricing for a group of products with different quantity levels.
The issue I'm having is that I'm trying to get JDE to only apply one discount when the quantity reaches a certain level.
For example:
0-50 items 10% discount
51 + items 15% discount to all items

What I'm trying to achieve is if the order is for 51 items I want the 15% to applied to all 51 items what JDE will do is apply 10% discount to the first 50 items then 15% discount to 1 item.
Is it possible to set up pricing like this in JDE?

Thanks in advance
