We have released Clone Dashboard functionality. You can now clone an existing dashboard to create newer one and modify them to suite your needs.
To clone a dashboard goto Home > Dashboards > click on the hamburger icon > Clone. As you can see in the image below, we've also added a couple of other option namely, edit and delete for easier access to those options.
Make use of it and let us know. You can learn more about our latest enhancements in dashboards here.
