Maybe my challenge can be easily solved with other methods, but is it possible to have parameters (custom fields) on a relationship instance?
The challenge: two CPT (authors and publications). I'd like to give the authors the ability to handpick a couple of "publications highlights" that will be featured on their personal "frontend Single Page".
The challenge here is that a publication will have several authors, and it may be a "highlight" for some of its authors but not all.
Hence, I imagined that the relationship between an author and a publication would have the "highlight" custom field. Is this possible?
Or would it be better to have a custom field on the user that would allow to search internally for a given publication and insert its ID into that user repeatable custom field?
Thank you for your expertise.
