Sugar 8, sending email from Group address

Has anyone found a workaround to bug 79888? See: SugarCRM 

We can't set the sender of emails from Cases to the Inbound Email queue address and this is a problem for us. We do not want Customer Support and Technical Support emails coming from the individual's work email, rather from the Queue email address. This avoids any confusion when the customer is replying and keeps the conversation in the Case tracking system.

This is a showstopper for us and we cannot upgrade to version 8 as it is.

The Bug was changed today to an "Enhancement" and we need to find a workaround so that we can upgrade.

Any help is appreciated.

Thank you,
