> Thanks for writing "polymorphic associations". Not knowing that probably is why I struggled to find any info on it. We might have had a similar experience with this.

It wasn't strictly polymorphism, but the term you wrote led me to a article[1] where it mentioned "alternative parent". This alone instantly made the problem more understandable for me.
