Hi Dave,

If you add the Style to the document's template, it will be available for all new documents based on that template. For existing documents, IIRC, the Style will also become available if you set their 'Automatically update document styles' option. This can be a two-edged sword, though, as any Styles that someone has modified in the documents will be reset to what the template says they should be. Two alternatives are:
1. Use the Organiser to copy the Style from one document/template to another; or
2. Insert an empty paragraph of that Style in a document containing it, then copy & paste that paragraph to the document(s) you want it in.
