How to properly form a collection of geo objects in ymap?

Question

JavaScript

Task: to form a json array so that it creates collections of geo objects i.e.

var myCollection = new ymaps.GeoObjectCollection(collection, {preset: 'twirl#shopIcon'});

where collection is a geocollection object.
All examples describe that you need to make an empty collection and then push objects, but this option is not to my liking. It would be desirable to push at once in the designer all objects.

Found a solution using geoQuery
example:

var result = ymaps.geoQuery({
        type: 'FeatureCollection',
            features: [
                {
                    type: 'Feature',
                    geometry: {
                        type: 'Circle',
                        coordinates: [15, 15],
                        radius: 100
                    }
                },
                {
                    type: 'Feature',
                    geometry: {
                        type: 'LineString',
                        coordinates: 
                    }
                },
                {
                    type: 'FeatureCollection',
                    features: [
                        {
                            type: 'Feature',
                            geometry: {
                                type: 'Point',
                                coordinates: [12, 41]
                            },
                            properties: {
                              name: 'point'
                            },
                            options: {
                                preset: 'islands#yellowIcon'
                            }
                        }
                    ]
                }
            ]
      });

The first argument is not an array, but a feature. This object has an array children which describes GeoObjects
