AFAIK - not automatically. But there maybe a plugin that can do it, see ==>>

However, if you created an empty book titled "Metadata" for each Author with a set of metadata (e.g. Language:French; Tags:Melodrama, 19th Century; etc), then after adding a book by that author you would press Alt+A to list that authors books and use the Metadata Copy and Paste options to duplicate the metadata from the "Metadata" book to the book just added. This will replace any existing values.
To make it easy, I have the Keyboard Shortcuts for Metadata Copy and Paste options set to Ctrl+C and Ctrl+V respectively. And I had to set the
Exclude fields when copy/pasting metadata tweak appropriately.
