Add the ability to use FILTERS in "Get Data" in Power BI Desktop.

[pwickwire]

Today, the only way to add a filter to the GET DATA process in Power BI is to enter a custom query. that means that it is impossible to access large datasets without timing out because the "tagging fields" process pulls back too much data without a filter. Can you add the ability to use filters in the wizard, as you can now in Power Pivot, Tabular, and in Excel in the data designer wizard, into the Power BI Desktop app?
