How do you email statements to multiple contacts

Summary: We have over 6k accounts in one business unit that we are trying to email statements to. Each account at least have one contact with the responsibility type = Statements. Over 50% of these accounts have multiple contacts with the responsibility type = statements. When trying to send statements it is only going to the first contact on the account.

Content (required): I have tried adding all responsibility types to the multiple contacts (Bill To, Dunning, Statements).
