Specify fieldset for included relationship of the same resource type


According to JSON API spec documentation - you can provide list of fields to fetch for specific resource type. But what if I have a relationship of the same type but I want only specific fields of these object while having all fields for non relationship objects?


I have a “note” resource, which has “previousNotes” relationship which is also “note” resource

I am doing request in following way:


But the thing is, that I want all fields of notes but only title attribute for previousNotes

And according to documentation, I can add fields[notes]=title to the url. But this way both notes and previousNotes will have only title attribute in response because they are both same resource type.

Is there a way to specify fieldset not for whole resource type but for specific relationship(which is specified in include)?
