I would like to sync a single Character/Para Style from 1 file in a book to all other files

[wideEyedPupil]

I know we can:

1. identify a file in the book pallet in the left column and then Sync it to all other files;
2. use the "Sycronise Options…" menu item of the book palette to switch various things like para and character styles, master pages and so on, on and off during a book-wide sync operation
3. import single character and paragraph styles into a single InDesign document from another InDesign document using the respective pallete menus.

But what I want to do is only syncronise a single character or paragraph style to every documnet linked in the book file.

Or perhaps sync a small selection of character or paragrpah styles without having the issues with other styles that share names and base characteristics but have variations in each document being all made the same.

Is this another FR for Adobe?
