Multi-subsidiaries: Statement/General support

Lightcast is very interested in using statements, but has yet to find a solution that supports statements as they need. Her need is: "I have one customer, "Customer A", in Netsuite. Customer A has different, open invoices with my Subsidiary A and Subsidiary B.

I want to send one statement (one email) to Customer A that includes open invoices from both Subsidiary A and Subsidiary B. However, I want payments to Subsidiary A to route to Bank Account A and I want payments to Subsidiary B to route to Bank Account B
