In the help file for the quickfields custom process, there is an example usage:

Example: The Outpatient Surgery Clinic wants to populate Laserfiche fields with information from its patient records, but they are stored in a custom database that is not supported by Real-Time Lookup in Quick Fields. They do have an executable program that extracts the information from the database. They configure Custom Process to use this information.

This is very similar to what I want to do.  The problem is that it isn't clear how to populate template fields with the custom process.  It appears that you can populate the page text, text locations or page annotations.  Is the example inconsistent with the custom process or am I missing something?
