Create a book, with multiple documents - But sync master pages

Hi,

Question related to the body pages.

I have one document with all my Data and Related stuff.

Since i need multiple copies of these formats - i assigned multiple master pages to a body of a series of master pages, i call this Set of Master pages in Body #1.

Set of Master pages in Body #1 is repeptive, so i copied the related .fm file and imported it back into the book.

But if i want to edit my master page - i need to do this separtly for each document.

Is their a way to sync all body pages of documents in a book with 1 master page?

Kind regards
