Dont know if Im just being badly informed, but I havent managed to find out a way to handle this (using ID 1.5 PC-version):

-I have two (or more) 40-page layouts of a user manual that IŽd need to get into a single file. Its not absolutely necessary to do this as I could combine them when converted to PDF, but it would make them easier to manage.

Page setup and marginals etc. are identical, but the only way I can handle it at the moment, is to either bring them via clipboard, or drag&drop from one file to another, one spread at a time. Very, very inefficient, and gives a lot of room for errors!

So, does anyone know if theres a wiser way to get this simple task done? If Acrobat can do it in an eyeblink, I cant believe Indesign couldnt.
