How can I point Zorro to a new subaccount in OANDA?

The zorro docs say to generate a new API key, but that didn't work as the key gives access to ALL accounts and not individual accounts. When i load the second zorro, it still sees the first subaccount.

The OANDA docs state:
http://developer.oanda.com/rest-live-v20/authentication/
A personal access token can be used to access your account through the OANDA v20 API. Once created, a token will grant access to all of your sub-accounts. Please note, your personal access token is like a password, so you should guard it carefully. These tokens are unique to an OANDA account and should be stored securely.

Any suggestions on how to point a second zorro to a second subaccount?
