Not really answering your question, but just wondering in print....
My first recollection without verifying it is that the templates are for copying WBS and assignment data like tasks, assigned resources, efforts dates and the project financial properties are outside.
If that is correct then what you would like to do is not possible to do with templates and the options you have are the attribute defaults, process and XOGing.
If you do that then you should also populate all the other required fields in your version of CA PPM in project financial properties so that you do not create data that violates the integrity rules set.
