Calculate Last Working Day of each month in a Calendar Table

[kitpalmer]

I have a Calendar Table in PBI that I need to add a field for Last Working Day of each month.  I know for each date if it is a working day, holiday or weekend, but I need identify when the last day of the month falls on a weekend or holiday and roll transaction from those days back to the last working day to summarize several reports correctly.

My goal is to add a calculated column that would filter/group by "Year", "Month" & "IsWorkDay" and return the max date, so for each month I would then know the last working day.  How can I do this?  I tried the following, but it doesn't provide a unique date for each month, only the max date for the entire calendar:

New column to show the last working day

Last Working Day = 

VAR __YEAR = 'Calendar Table'[Year]
VAR __MONTH = 'Calendar Table'[Month]
RETURN
MAXX(
    FILTER(
        'Calendar Table',
        'Calendar Table'[Year] = __YEAR && 'Calendar Table'[Month] = __MONTH && 'Calendar Table'[IsWorkDay] = TRUE()
    ),
    'Calendar Table'[Date]
)
