You will need tabular editor for this to work , so google tabular editor and download it form their github repo. 

this is the syntax:

var templateDax = @"/* ----- DAX template begin ----- */
VAR logicTest =
  COUNTROWS(DISTINCT(FILTER(ALLSELECTED(YEARS[YEAR]), YEARS[YEAR] = %YEAR% ))) = 1
  
/* TODO - Add remaining DAX code here */

/* ----- DAX template end ----- */";

var years = new[] { "2010", "2011", "2012", /* ...etc... */ "2020" };
foreach(var year in years)
{
    var measureName = "measure_" + year;
    Selected.Table.AddMeasure(
        measureName,
        templateDax.Replace("%YEAR%", year)
    );
}
