And is this native bidirectionality built-in if Events were to be a Taxonomy?
Ie between
* the Term and Posts? (add posts Relationship to Term field group, and add Term selector to Posts field group?)
* the Term and Terms (add different Term selector for each Taxonomy to the opposite Taxonomy’s field group?)
* the Term and Users (add Term selector to User profile field group, and add User selector field to the Term field group?)
Is there then a two-way relationship between any of those things?
