Alexandria – Not sure exactly what you mean by the Prod Template area. There are several types of templates within Project Server; Site Templates, Schedule Templates, List templates (SharePoint) to name a few.
If you are looking to create document folders you can do that in any SharePoint site. If you want to group project schedules, you’ll need to create a custom field (Program?) and use it to group projects within the same program in a custom Project Center view. Alternately, you could create a Master Schedule with your sub-projects inserted into it.
