GUI Interaction - Allowing Users to Upload a Criteria Set to Query

[rodrigj]

Does Power BI allow designers the ability to program widgets to allow users to upload a file of criteria?  For example, I want to allow the user to upload an excel file with a set of criteria about an employee and Power BI return the eligible employees in a drop down menu. 

I know how to do this in Excel VBA given a file, but is it possible for Power BI to replicate this functionality with live data and produce an interactive table that users can select from a drop down menu and that selection would cause another filter to activate with another drop down menu?

So you can build custom visuals using the the Typescript SDK and in those you could add a button that triggers a file upload (the synoptic panel from OKViz does this sort of thing). And you can build custom visuals as slicers so that they filter other visuals, so this *may* be possible, but I can't say I've ever seen anyone attempt anything like this before.
