Continuing the discussion from [Polymorphic relations. When creating relation, ability to have many Types from which to choose, and not just one Type](https://community.fibery.io/t/polymorphic-relations-when-creating-relation-ability-to-have-many-types-from-which-to-choose-and-not-just-one-type/425):

I found that everyone is as curious as I am：Can I set an optional fields to let me choose a different database to relate. For example, I put different scenes tags as different database . At this time, I hope any book can choose which scene tag to classify.
