Editables inside Layergroup

[Meirur]

In a larger (tab driven) project I'am adding all stuff to L.Layergroup for easy managing the Layers.
If I'm using
this.Map.editTools.startCircle()
then the circle will automatically added to map.
I', looking for a solution to add the circle to my own Layer like

this.Map.editTools.startCircle({target: myLayer})
Any inspirations?

Edit:
This

 startCircle: function (latlng, options,target) {
            latlng = latlng || this.map.getCenter().clone();
            var circle = this.createCircle(latlng, options);
            if (!target) target = this.map;
            circle.enableEdit(target).startDrawing();
            return circle;
        },

doesnt work, because later (in L.Editable.CircleEditor) the lib try to use this.map.project and this fails
