Can PowerBI pull data from a SharePoint Online Content Type and present data from all sub-sites

Hi,

I want to roll-up data from across all SharePoint Sites, that have the same content type. (This is simliar to SharePoint Content Query Web part, however the web part is limited to only on coloumn of the Content Type).  

For Example, there is a content Type Called "Contracts" it has 3 columns, Contract Name, Funded value, Contract value.  I want to display this data across all "Contract Sites" (each contract has its own site

Thanks
