Great module!
Alas, what I am wanting to do is show not just one but several fields from a referenced entity on the parent entity. Since this is a field formatter, there is only one instance of the field, on the parent entity display config. So this is not possible to do, correct? Note, I would need the different fields to not necessarily be adjacent to each other, so there would be a referenced field, a parent field, then another referenced field after that.
I don't think this is possible but wanted to check since the module seems like it would be of much greater value if it was.

It looks like I'll be able to do what I need with https://www.drupal.org/project/ds_chains →
Leaving this here in case this helps anyone else.
This module has a really elegant interface so I definitely see its place.
