Buy from Sourcing Assignment in Replenishment Planning at Item Subinventory level

Summary:

Use case :

Every time a new Subinventory created , 'Buy From' sourcing rules need to be defined at the item-location ( Item-Subinventory) level.

Since the client is having 1500 RP items , 150 Orgs and each Org has 30 Subinventory per Org, creating sourcing assignment at item-Subinventory level ,

each time a new Subinventory created is too much work for the user. ( 1500 records per Subinventory)

What is the best way to manage this situation.
