Many of the products in the marketplace, including ToA, were released well before the Charactermancer functionality was created, and compendium integration for adventures wasn't released until they had solved incorporating Charactermancer stuff I believe. The first adventure to include Compendium support was Ghosts of Saltmarsh. Any product you buy on the marketplace will list whether it includes Compendium or Charactermancer functionality as part of the description. Devs have mentioned going back and adding this functionality to older products, but they have never given a timeline on if/when they might do this.
