In the same way that it would be tedious to re-enter all your player settings every time you created a player, it would be annoying to have to add your favorite players one at a time to each new document. FreeStyle has a short-cut: The Ensemble Library.
An Ensemble Library Entry is a collection of player templates that can be added to a document in one shot. Whenever you create a document, FreeStyle asks you to pick an ensemble library entry. It then creates players from each of the player templates in the ensemble.
The Edit Ensemble Library command in the Setup menu lets you setup and modify your own Ensembles. Get balloon help in the Edit Ensemble Library dialog for details on how to edit the library.
