Retail POS: Complete the Customer's Financial Dimensions in a Customer creation from POS AX

Hi

   We have POS AX with AX 2012 R3 CU8, and we need complete the Financial Dimensions of each Customer while we are creating them directly from the POS AX. It´s possible?

   Create a Customer from POS AX, and then complete the Financial Dimensions in AX ERP, is not a option.

Thanks in advance.
