How to display employees of a particular molga via radiobutton in alv report?

I have an ALV Report in the output which is displaying fields from 4 different infotypes (PA0000, PA0001, PA0002, PA0006). I've attached a screenshot of my selection screen below. I have 2 radiobuttons for USA and India (USI) employees. If i click on US radiobutton it should show only those employees which have molga = 10 and similarly for India radiobutton it should only show employees which have molga = 40. How do i achieve this?
