C4C/ERP: Only send Customers to ERP ECC, if specific fields are changed

Hello all,
we want to create KUT fields for segmentation purpose. These fields are maintained in another system.
If these fields are updated in the customers, all of them are replicated to SAP ERP ECC. Hence, this leads to high traffic. The KUT fields for segementation are not relevant in ERP, therefore we dont need to replicate to ERP when these fields get changed.
We use the standard Business Partner Integration via CPI iflow.

Is there an option as in ERP (transaction BD52) to configure which changes of fields are relevant?

Thanks!
Best regards,
Deborah
