Reply To: Stop Importing Paragraph Styles from other Documents

If the old styles are of no use to you, import all your documents into a new file, then Delete Paragraph Styles. Load your new Paragraph Styles from your Template.

If you have a lot of documents, using the Book feature is a possibility (using Find/Change or probably a GREP).

Basically, it’s a name game. If it’s easier to temporarily change your Template Paragraph Styles, you can delete the old ones and replace with the new names.
