Series file naming

How do you set the file naming convention for a series?

The support area doesn't list anything other than how/where to open it. In the VIDEO tab there is a single listing for <series> that can't be modified. If I "ADD/EDIT" and create a new one its not available to "Choose" as the current option.

It all seems to be setup for Audio far more than video in the options for file saving. Can anyone tell me how to get a simple <series title season# episode# - title.ext> setup please?
