CustomField

Hello, How do you populate a field when creating a package from a template? I don't want to define the field location in my code. Instead I need to simply pass along the value that should appear in the correct location. Some of these uses will be for read only fields and some for pre-populating an input that is required/optional. I've successfully setup a template using the online interface and placed a field with the name "CustomField1" inside the template.
