Employee responsible in Receivables WoC- ByD

Hello gurus

I need that the Employee responsible-sales of a customer master data (see the screenshot)

could be displayed in the customer account Monitor in Receivables WoC.

The aim is to identify the Employee responsible-sales of open items, adding a new column of the table or displayed below in Details part.

I don't know if there's a way doing this in adaptation mode and how, or if I need SDK.

Thanks

Regards
