Dynamically create as many What-if Parameters as there are values in a column

[Anonymous]

Is there a way to dynamically create as many What-if Parameters as there are values in a column?

My Goal: in my sample dataset, I have N countries. I want to create N What-If Parameters, so that I can apply a unique what-if parameter to each country. The number of countries would change from time-to-time. 

Is there anyway this is possible in Power BI? If not, what are my alternate options to nominate a unique value for each country?

@Anonymous , I think you have to create multiple what if

But how do I create what-if parameters dynamically as the number of countries would change?
