If you are writing a long document e.g. a book or thesis, create a separate Word document for each chapter. In each chapter, insert your citations to link them to references in your EndNote library. You should keep the chapters separate until the latest moment before merging them to create a document with a single bibliography.
This video tutorial above from the University of Queensland Library (CC BY) demonstrates the more advanced functions of EndNote 20 that may be useful when writing long documents. This includes, editing styles, using journal term lists, and merging multiple chapters. Combining (or merging) chapters into one document commences at timepoint 27:32.
