WEB ADI Integrator Interface Attribute View Groups

Hello,

I have an existing custom integrator that collects several columns to feed to the AP Invoice Interface.  The input file is in excel.  The interface type is TABLE.  There is one custom attribute mapped to the Flex Fields GROUP (Segment1..6).

The current process is in production and it works as planned and design.  There is however, a request to make that attribute such that when the excel sheet is opened and a certain column (Invoice type) is populated by the users, the DIST ACCOUNT Flexfield mapped to the Group of type: Key Flexfield mapped to the component name: OA_FLEX Component gets populated by default with 6 accounting SEGMENTS.
