connect to additional tables

I want to connect directly to Dynamics 365 from Power BI Pro, and then use that dataset for my Power BI Desktop source.  I've connected to the Sales Analytics for Dynamics 365, but it does not include all the tables I need to use. 

1. Is there a way to connect to Dynamics 365 directly, without having to use Apps that are missing tables I need?

2. If so, how do I do that?

or

3. Can I add the tables I need to Sales Analytics connection I already have?

Many thanks!
