Using a custom symbology renderer with a geojson Feature Server

[jptheripper]

I am running a simple provider that reads geojson from a url and creates a featureserver. I am trying to predefine the symbology using a unique value renderer

I cant seem to find where to pass the renderer info.

If i edit the point.json file in
\node_modules\featureserver\templates\renderers\symbology\point.json

It works perfectly, however that affects all featureServers.
