Is your feature request related to a problem? Please describe.

Google can't see all the possible relationships between the books. So we are loosing traction.

Describe the solution you'd like

Adding cannonical tags to all the 'pb_is_based_on' (cloned or versioned) books.

why you think the feature request is something we should consider?

Boost of the SEO.

Additional context

If 'pb_is_based_on' setting is activated in a book and if URL is set in a page (public post) we print this cannonical URL which we inserterd as a HTML tag.
Problem 1:
Block the SEO framework functionality related to printing cannonical tags.
Problem 2:
If the book is a translation we can not print this cannonical tag.
