ASCP - is there any functionality in ASCP to purchase item from multiple source and price break

Hi

please let me know if the scenario listed below can be handle in ASCP

Create 3 BPA for 3 suppliers; each blanket has 3 price break define as follow

supplier	Unit Price Break
qty	1 >  20	20 >100	100 > 500
SMDP	612	600	590
SMP	614	590	490
TECHLASER	620	600	400

we can manage the sourcing rule so that the planning can generate a supply based on the allocation percentage

but, We want to know, if there is a way to create a sourcing rule so that, the planning will suggest supply based on the best price along all the price break defined for the item

Thanks and Regards

Michele
