Share Taxpayer ID - non parent/child relationship

Summary:

Business has a scenario where two suppliers share the same taxpayer ID. These two suppliers are children of a third supplier that the business does not transact with and has not been set up in the Supplier Master. Is it possible to establish a non-parent/child relationship with these two suppliers so that they can share a tax id? Or does the parent need to be set up? If the parent is set up and the parent/child relationship established, will the 1099 details be associated with the parent even though the transactions will be on the children?
