All we have is Question #10 from the second FAQ document that was issued in April. That seems to allow for that kind of document.
Question 10: Identification and verification: Certification when a
single legal entity customer opens multiple accounts
If a legal entity customer opens multiple accounts at a covered financial institution
(whether or not simultaneously), must the financial institution identify and verify
the customer’s beneficial ownership for each account?
A. Generally, covered financial institutions must identify and verify the legal entity
customer’s beneficial ownership information for each new account opening,
regardless of the number of accounts opened or over a specific period of time.
However, an institution that has already obtained a Certification Form (or its
equivalent) for the beneficial owner(s) of the legal entity customer may rely on
that information to fulfill the beneficial ownership requirement for subsequent
accounts, provided the customer certifies or confirms (verbally or in writing) that
such information is up-to-date and accurate at the time each subsequent account
is opened and the financial institution has no knowledge of facts that would
reasonably call into question the reliability of such information. The institution
would also need to maintain a record of such certification or confirmation,
including for both verbal and written confirmations by the customer.
