LOY Engine Process Batch - Custom process?

Hi!

We need to "stamp" the "Partner Price Amount" in every accrual transaction.

In the realtime process is not a problem because we could add this especification in LOY Engine - Process Transaction Workflow

but the problem is in Batch mode, ¿How can we add this value in a transacction when is the engine who process it? is there a better solution for this especification?

(We have read in this document (Doc ID 1532344.1) that we can't invoke a custom Workflow in batch mode).

Thank you,

Kindly regards.
