Can't add additional attachments when forwarding an email as an attachment

Using the SOAP API, sending additional attachments when forwarding an email as an attachment fails.  The original message is being sent as an attachment to an address that could be either internal or external to the sending GroupWise system.  The forwardRequest function is being used to forward this item and the "default peek message attachments" view is being used to get email data.  Adding any additional attachments to the forwarded message, even with a subject change, sends the message however only the original attachment(s) are sent and the additional ones are not there.

This has been reported to engineering and will be considered for a future release of GroupWise
