Dynamic data source

Hi

I don't think what I am trying to do is possible but I thought I would ask anyway.

Very simply I have a SharePoint site template which contains an embedded Power BI report to display a burndown chart from data held in the site. Obviously each time I create a new site I want it to retrieve data from it's own list, so I need to be able to pass the data source to the embedded report some how.

Like I said I don't think this is possible with Power BI, but I may be wrong.

Any help is greatly appreciated.

Thanks
