Recurring Transactions are an awesome feature you can use to automate your bookkeeping where possible. If you're trying to cc two different people on your recurring invoices, I'd be happy to explain how this works.
When you create a recurring transaction, the transaction will continue to reflect the same information each time it occurs. It sounds like you'd like to cc a different person on the same invoice. If you add a cc or bcc on your recurring transaction, this can't be changed the next time the transaction occurs.
You're welcome to create two different invoices as a recurring transaction with different cc's.
