Is there a way to import some (not all) same name para styles to multiple chapters (files) in a book overwriting old settings without apply/update all function in Frame Maker vs. 12?

Is there a way to import some (not all) same name para styles to multiple chapters (files) in a book overwriting old settings without apply/update all function in Frame Maker vs. 12?

I have a book that has 25 chapters (files) and need to 5 to 8 para styles updates and only want these styles updated. Can these files be updated globally?

I’ve yet to figure out how to manage updates globally of same name para styles without performing the following function for each individual chapter in the book:

1. Open the file
2. Paste the updated para styles (5 to 😎
3. Open each para style
4. Apply
5. Update all
6. Repeat this function for each chapter in the book for each para style.

It is very time consuming to complete this function for 25 individual files. For five para style updates for a book with 25 chapters equates to 125 functions—there must be a more efficient process to manage style files.

Any suggestions are much appreciated on how to manage style updates in a book with 25 chapters?
