1099 Reporting for BU with multiple supplier sites

Summary:

We have multiple suppliers who have 2 or more sites per business unit. Only 1 site requires 1099 reporting. Is there a way to automatically remove the Income Tax designation on the site that does not require 1099 reporting?

Content (required):

Example: Company ABC has 2 Business Units - BU1 and BU2

Company ABC is marked 1099 reportable as BU1 has 1099 reportable transactions

BU2 has 1 site: Not 1099 reportable; Income Tax Report Box is NOT checked

BU1 has 2 sites: Main1 and Main2

Main2 requires 1099 and has the Income Tax Reportable box checked

Main1 does not require 1099 and does not have the Income Tax Reportable Box checked
