Label on marker doesnt exist property

My problem is i cant put a label for the marker type MarkerOptions, and if you look inside the markeroptions code you will see there isnt a property label. How can achieve the same effect a number on the marker for example. i dont want a infowindow i know that i can achieve that with the title property but i dont need that.

export interface MarkerOptions {
    /**
     * The icon image url or properties. Also you can specify HTML Color values. Alternatively you can specify the image as Base64
     */
    icon?: any;
    /**
     * The content of the infoWindow.
     */
    title?: string;
    /**
     * The snippet of the infoWindow.
     */
    snippet?: string;
    /**
     * The position of the marker.
     */
    position?: LatLng;
    /**
     * 	Specify the anchor of the InfoWindow
     */
    infoWindowAnchor?: number[];
    /**
     * Set true if you want to enable to drag the marker. (Default: false) Important! Drag starts after long pressed on the marker.
     */
    draggable?: boolean;
    /**
     * 	Set true if you want to use a flat marker. (Default: false)
     */
    flat?: boolean;
    /**
     * 	Set rotation angle. (Default: 0)
     */
    rotation?: number;
    /**
     * Set false if you want to hide. (Default: true)
     */
    visible?: boolean;
    /**
     * Specify the options for title.
     */
    styles?: any;
    /**
     * Which animation to play when marker is added to a map.
     */
    animation?: string;
    /**
     * 	iOS only, Plugin Version >= 1.3.3 Higher zIndex value overlays will be drawn on top of lower zIndex value tile layers and overlays. (You're able to run this on Android, but it will have no effect)
     */
    zIndex?: number;
    /**
     * Set to true to disable auto panning when the marker is clicked.
     */
    disableAutoPan?: boolean;
    /**
     * Function to be invoked when the user clicks on the marker
     */
    markerClick?: Function;
    /**
     * Function to be invoked when the user clicks on the info box
     */
    infoClick?: Function;
}
/**

What do you mean by that?

I ended up creating my own pins as images
