Form Entry for Power BI?

I'm not sure if this is even doable - will Power BI (in the future) give the ability to have form entry? For instance you have a data set, you create reports/ dashboards and send it out to the end-user. However - that report can be processed several different ways and may require end-user input that determines the outcome of the report. Example: Commission Rates - I set up a report that pulls Total Sales dollars per rep for the month. However, depending on rep level - each one may earn different commissions rates. So I set up the base report and leave field entry for the end-user to put in the the commission rates based on the rep. Then the report calculates based on the Sales Dollars and the rates entered by the end-user. IS THIS POSSIBLE?
