IMAP email migration

I'm in the middle of migrating mailboxes from an IMAP server to 365.

 

On the IMAP end, I have a user who has 2 email accounts with 2 (large) mailboxes and wants them merged into one Exchange user mailbox / account.

Is this possible via standard migration tool ? I've migrated the first IMAP mailbox in one CSV file, but when I created a second CSV for the other I not unsurprisingly got the error:

"Error: UserDuplicateInOtherBatchException: The user 'blah' is already included in migration batch 'blah' Please remove the user from any other batch and try again."
 
I'm hoping to try and avoid a manual export/import of the second IMAP account if I can help it...
