Create a view that UNION's all the tables (if they have different structures you'll need to make them similar but it's easy to do in the view's definition). Such a view should be imported into Power BI. To refer to the data of a particular table, you can have a column inside the view that tells you which table the data comes from. Then to do what you want it's just a matter of proper filtering put on the imported table. In general, having myriads of tables with the same structure is not what Power BI likes. Try to always standardize.
