Using Logi Reports to populate .pdf Document Properties-Custom Properties with Name-Value pairs extracted from TrakCare database for patient invoicing

We are investigating option of populating .pdf Custom Properties Name-Value pairs with episode/billing information from the TrakCare database, using Logi Reports.  Resulting .pdf would be stored in a designated network folder.  Would welcome suggestions on feasibility / technique to achieve  / code to achieve (or alternative approach).

Intent is for further (watcher) process to detect new .pdf file in network folder and determine actions and/or process flow based on Name-Value pair information in pdf's Custom Properties.
