Power Bi Report Builder

Hi

It´s any possibilty of conect the Local Report Builder to a ODBC connection?

Any connector to PostgresSQL or Athena (AWS)?

Something else please, when trying to edit a report in my local machine connected to a DataSet published in power BI service, it´s unveliable slow even to retrieve any filed, it´s there any trick to improve this, or only depends on the DataSet size?

Thanks in advance for your time.
