Adding custom fields onto ConnectionEdge

[silidos]

Currently trying to add custom fields onto a ConnectionEdge type. The schema parser will automatically look to the relay Edge type for a field I have defined alongside node and cursor. To my understanding, the only way to go about adding this custom field is to create custom relay connection classes. Is there a way of telling the schema parser to look somewhere else to resolve this field in an Edge or will it always try to resolve it in an Edge type as its apart of the relay connection? Attached is an example of what I'm trying to achieve
