BEST PRACTICE: How to add CCK fields to Smartdoc Template?

[#1]

I am looking at the best practice way to add custom cck field added to the smartdoc content type into the actual smartdoc template.

For example, say I add 'State' w/ field name 'field_state'.

I understand how to display it with views I just need to have it automatically included upon Smartdoc upload.
