Create Report from multiple databases

Create Report from multiple databases

I have read through the Forums and it looks like the ability to create reports from multiple database was on the roadmap a year ago. Has there been any progress towards this end? I have 2 large (# of tables/relationships) Creator databases that are downloaded to Analytics. I need to combine fields from the two to create multiple reports. 

It looks like the only way to do this a year ago was to create your own API and store them together and then create reports. Has this been resolved? That is a pretty daunting task.

Thanks.
