When somebody starts a new family, they will often have a project open. Hopefully, that project was started from your office template.

In the family, go to the Manage tab > Transfer Project Standards and choose to transfer the Fill Patterns from the project to the family. Done! After doing what you want with the new family, you can always delete out the unwanted fill patterns. But the extra fill patterns will probably only add a couple kilobytes (a couple dozen at the most) to your family file size.
