Sending statements when using consolidated payments

Hi there, we use consolidated payments as we have multiple customers where the individual stores order, but then the head office does the accounting / makes the payments. This works well when receiving payments, but we have issues when sending statements. If we send a statement to the top level parent customer with the 'Consolidated Statement' box ticked, the head office receives a single statement, but there is nothing on the statement that tells them which invoice relates to which store in their group. I cant see an obvious way to add this information to the statement.

If we send to the child level accounts (stores within the parent group), as they all have the same 'Accounts' email address (which is the head office accounts address) the spam filters on NetSuite seem to kick in, and the head office only receive a statement for one of their stores.
