Reusable App for SharePoint to embed Dashba

[Yaostha]

It would be great if we there is a reusable free app from PowerBI to consume in SharePoint to embed Dashboards or Tiles. The PowerBI webpart works only for Reports and unable to change the sizes. If there is an app which will list the dashboards from work space and allow the site admin to configure the dashboards on a page. This is required since many organisations switching to O365 and SharePoint Online and analytics is gaining importance.
