Customizing with Relations, Sort, & Filters
Instead of adding Relations one-by-one to Objects, you can batch-add them to your Set by clicking the filters on the right side.
Here you can toggle on/off any relations that you would like to see, add another relation or new relation, and edit the view of the Set here.
This sections acts as your sort & filters.
You can add any Relations to be automatically added to your Objects, by adding them in the creation process of your Type.
See more about how to Create a New Type here. Underneath the title & template section of the new Type process you'll have the Relation options.
