User's Manager in BPM

We have a business process that requires the assigned user's manager to be assigned a task to carry out some required actions. We cannot see how this can be achieved within the Business Process Definition.

However, it is possible to construct an Email Template with the assigned user's manager in the email address fields. But it is not possible to insert a token for the assigned user's managers name in the body of the email template.

We noticed a similar problem with BPM Email Templates where you cannot specify a specific user, you must use a Team or Role.  

Does anyone know how to address these questions or are they functionality limitations intended or otherwise ?
