Using VNDR_ID_EXCEL to load withholding information

Hello,

we discovered that we can add Vendor locations using VNDR_ID_EXCEL (using Update Action). This contradicts EAP: Is It Possible to Add Vendor Location Using EXCELTOCI for Existing Suppliers (Doc ID 2774473.1).

We are on PT 8.58, PUM35.

The question is can we use it to load the Withholding information for existing Vendors for the record PS_VENDOR_WTHD_JUR, PS_VENDOR_WTHD_JUR? According from an old 2013 document EAP: Clarification on Vendor Upload ExcelToCI for Withholding information (Doc ID 1263619.1) - we cannot. However, as with vendor location - this might have changed.

Questions:

1.Is is possible to upload Withholding information to VENDOR_WTHD and VENDOR_WTHD_JUR via ExcelToCI in either a delivered or custom Component Interface?
