Time Intelligence with Power Query

Mr. Miguel Escobar has written a pattern on his blog under the subject "Time Intelligence with Power Query"

brought us the same period of dates but for last year. it also featured a function like "TOTALMTD" giving an accumulative value based on month-to-date. What I'm thinking about is it would be great if both "TOTALQTD" & "TOTALYTD" could be incorporated too providing an accumulative value based on a year-to-date, quarter-to-date as well. Hopefully Miguel would like to share it with us on the forum.
