Can multiple inbound Sales Orders be created through a single CMK inbound transaction?

Can multiple inbound Sales Orders be created through a single CMK inbound transaction? If so, what configurations or setups are required to enable this?

We attempted to create an inbound Sales Order with multiple Purchase Orders. While the transactions were successfully created in CMK and the Load Interface job completed without issues, the Sales Order Import job failed. Upon investigation, we discovered a difference in the "ProcessingConfiguration" node generated internally by CMK for multiple Sales Order requests compared to a single Sales Order request. Several tags, such as ConfigurationData1, which holds the value for RequestingBusinessUnitIdentifier, are missing when multiple Sales Orders are submitted.
