Multiple accounts with afew

I've recently started using Notmuch. One thing I am missing is to setup afew to move messages between folders after tagging them with Notmuch. It all works fine with just one account under ~/Mail, however, I want to operate on 3 separate accounts which would be ~/Mail/Account1 ~/Mail/Account2 ~/Mail/Account3 How do I configure afew to move messages based on tags in specific accounts? afew just does not see anything in the subfolders/subaccounts. Sample config: [MailMover] folders = Account1/INBOX Account2/INBOX Account3/INBOX Account1/INBOX = 'tag:spam':spam Account2/INBOX = 'tag:spam':spam Account3/INBOX = 'tag:spam':spam Obiviously Account1/INBOX is not a valid variable name. Perhaps afew cannot deal with multiple accounts?
