There is a Text Insert item for the Title:
Text menu > Inserts > Title
You can insert it in various locations, using various fonts, sizes and styles - all in the same document.
You can edit the insert item (e. g. correct a typo), and all its occurences will be changed in one go:
File menu > File Info...
When you create a new document with the Document Setup Wizard, the Wizard automatically writes the Title to the File Info box.
