After syncing a linked Word document, what must I redo?

Using RoboHelp HTML 11. I'm going to try making a project by linking a Word document instead of importing. Before I do, I want to be clear: what changes in the project will be lost, and must be re-done, each time I update the link to the Word document?

For instance, will I have to reapply the Master Page to all the topics? How about the TOC?

Thanks.
