I have a package of documents (almost entirely Word and Excel) that I give to a client at the beginning of a project. Every time we get a new client I have to go through each document and add the client's name and logo and it takes a lot of time. Is there a way I can add it once and have it update each document automatically? Like with a macro or something? Or do I have to create some kind of Access DB in order to do this?
