JSONAPIAdapter - Overwrite buildURL

Hej Ember Community, I want to overwrite the buildURL Function in my JSONAPIAdapter. But i am not sure how to do that.

what i want: i want to query for something like that: var backendData = yield myStore.query('aggregatedresponsetimeinfo/info', {limit: this.get('limit')});

the / is the problem here. you only can insert the modelname

then i want to use aggregatedresponsetimeinfo as the model and the url should be like namespace + aggregatedresponsetimeinfo/info

if i overwrite the function

    buildURL (modelName, id, snapshot, requestType, query){
    		console.log(modelName);
    		console.log(id);
    		console.log(snapshot);
    		console.log(requestType);
    		console.log(query);
    		return "";
    }

how can i call the real buildURL function inside my overwritten buildURL function ?
