Route between multiple markers - google-maps

Question

Is it possible to plot multiple markers as well show routes between these and origin? For example: I have one origin and four different destinations. I want the routes to be shown between the origin and the destinations, so that it is A to B, A to C, A to D, A to E. Can this be done? I have only seen the option to display the route between two points or to calculate distance between multiple. I want to be able to calculate the distance as well as showing the route on the map.
So far this is what my code looks like:
$("#submit").click(function() {
var values = $("#street").val();
var geocoder = new google.maps.Geocoder();
var address = values;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
}
service = new google.maps.DistanceMatrixService();
var origin = new google.maps.LatLng(latitude, longitude);
var destination = new google.maps.LatLng(48.856614, 2.352222);
var destinationb = new google.maps.LatLng(41.385064, 2.173403);
var destinationc = new google.maps.LatLng(44.584910, 5.133122);
var destinationd = new google.maps.LatLng(45.365187, 0.647394);
var destinationIcon = 'data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%2278%22%20height%3D%2238%22%20viewBox%3D%220%200%2038%2038%22%3E%3Cpath%20fill%3D%22%23333333%22%20stroke%3D%22%23ccc%22%20stroke-width%3D%22.5%22%20d%3D%22M34.305%2016.234c0%208.83-15.148%2019.158-15.148%2019.158S3.507%2025.065%203.507%2016.1c0-8.505%206.894-14.304%2015.4-14.304%208.504%200%2015.398%205.933%2015.398%2014.438z%22%2F%3E%3Ctext%20transform%3D%22translate(19%2018.5)%22%20fill%3D%22%23fff%22%20style%3D%22font-family%3A%20Arial%2C%20sans-serif%3Bfont-weight%3Abold%3Btext-align%3Acenter%3B%22%20font-size%3D%2212%22%20text-anchor%3D%22middle%22%3E' + "" + '%3C%2Ftext%3E%3C%2Fsvg%3E';

To display the routes, call the directions service. Modified function from the example in the documentation:
function calculateAndDisplayRoute(start, end, map) {
var directionsService = new google.maps.DirectionsService();
var directionsDisplay = new google.maps.DirectionsRenderer({
map: map,
suppressMarkers: true,
preserveViewport: true
});
directionsService.route({
origin: start,
destination: end,
travelMode: 'DRIVING'
}, function(response, status) {
if (status === 'OK') {
directionsDisplay.setDirections(response);
} else {
window.alert('Directions request failed due to ' + status);
}
});
}
calculateAndDisplayRoute(origin, destination, map);
calculateAndDisplayRoute(origin, destinationb, map);
calculateAndDisplayRoute(origin, destinationc, map);
calculateAndDisplayRoute(origin, destinationd, map);
