How to Split Sales Order Lines Based on the Supply Type

Hello

Our ATP and sourcing rules are set up to

reserve the available quantity in the inventory organization

if there are no available quantity a TO is generated to get items from other organizations

if there are no available in any organization a PR is generated

How do we make each SO line be split based on the supply type?

Meaning if line 1 is created for 50 qty of an item while 10 in current org and 20 in other org, the line should split into three lines with three different supply types

1-1 On-hand

1-2 TO

1-3 PR

Thank you
