Create column with number of occurrences in another column in Power Query

[joe_4818]

Hello, 

I want to be able to create a calculated column in power query (not in power BI), to count the number of occurrences of the value in that row from the entire table.  For instance, there would be a 2 in a new column for the first two rows, as that string is repeated twice.  I was able to do this in Power BI, but I need to do it in Power Query before loading my data.  Below is what worked in Power BI....
