ChangingDisplay Format Based on a Slicer

Hi there, I was wondering if I could make a user select a unit, e.g., Mio, Tsd and it would automatically change over the report. I was thinking about making a measure with a switch based on a parameter. But this would mean I would need a lot of measures. In the picture below, I show what I want. So my question is: Is there a more elegant way or an option that I missed? Thanks for taking the time to read this. 

Cheers Arne.
