Adobe Analytics Report Builder connector - data set refresh

Hi there, 

I'm hoping someone can help me with the adobe analytics report builder connector? 

I've built out my workbook in excel using report builder (and have laid columns out in way that can best be used in Power BI) , and have scheduled it to refresh each morning (as well as pubish to power bi). However, the dataset I can see in Power BI service puts each report builder query into a new table, and breaks all my formatting, so i can no longer build visualisations the way I need to. 

Is there another solution here? At the moment, the report builder files sends to my email, i then save the new file over the old one, refresh the data on Power BI desktop and re-publish to service... but hoping to be able to automate! 

Any advice would be greatly appreciated! 

Thanks,

Sonia
