Ok, I'm not a script writer, otherwise I'd have this automated already. I need a quick assist in the most basic steps possible.

I have a SharePoint form library using InfoPath based forms. I have a "Public" template for my customers which submits to a "Private" library, through very granulated permissions so they cannot view the library. The Private library has it's own template based on the original Public template. This way I can transition one form's information seamlessly to the new template. The new Private template would have all of the internal details that we do not want the customer to see, but also all information fron the customer-filled Public form.

Is there any way to default all items opened from the Private library to use the Private Template, even though they were submitted form the Public template?
