R12 Encumbrance: Multiple Balancing Segments without enabling the ledger option Balance Cross-Entity

Hi there

We have several operating units, each of which is represented by a unique balancing segment value in our chart of accounts. The Reserve for Encumbrance account can only be set to a single value for each ledger. All the operating units post to this single ledger. When the create accounting process is run in each operating unit, it will create encumbrance accounting entries which cross balancing segments (which is not what we require). Is there a way to ensure that the balancing segment for the "Reserve for Encumbrance" account matches the same balancing segment value of all the other accounting
