Is it feasible at all to default Supplier and Supplier Site based on Item & Org for Drop Ship items?

Hi,

Our requirement is to achieve Supplier and Supplier site for drop ship items based on a combination of Drop Ship item and Business Unit (BU), as our supplier sites are BU-specific.

I understand that for back-to-back scenarios, sourcing rules can be assigned at the 'item + org level' to default suppliers and sites. However, for drop ship scenario, is it feasible at all to achieve the same?

If this is not supported out-of-the-box, I’d appreciate any suggestions on best practices or workarounds.

Thanks in advance for your insights!
