Exclude weekends on a weekly report using autocalendar

[#1]

I'm using the autocalendar function for a graph dimension but I don't know how to exclude Saturday and Sunday. The autogenerated code is:

[autoCalendarr]:

  DECLARE FIELD DEFINITION Tagged ('$date')

FIELDS

  Dual(Year($1), YearStart($1)) AS [Year] Tagged ('$axis', '$year'),

  Dual('Q'&Num(Ceil(Num(Month($1))/3)),Num(Ceil(NUM(Month($1))/3),00)) AS [Quarter] Tagged ('$quarter', '$cyclic'),

  Dual(Year($1)&'-Q'&Num(Ceil(Num(Month($1))/3)),QuarterStart($1)) AS [YearQuarter] Tagged ('$yearquarter', '$qualified'),

  Dual('Q'&Num(Ceil(Num(Month($1))/3)),QuarterStart($1)) AS [_YearQuarter] Tagged ('$yearquarter', '$hidden', '$simplified'),

  Month($1) AS [Month] Tagged ('$month', '$cyclic'),

  Dual(Year($1)&'-'&Month($1), monthstart($1)) AS [YearMonth] Tagged ('$axis', '$yearmonth', '$qualified'),

  Dual(Month($1), monthstart($1)) AS [_YearMonth] Tagged ('$axis', '$yearmonth', '$simplified', '$hidden'),

  Dual('W'&Num(Week($1),00), Num(Week($1),00)) AS [Week] Tagged ('$weeknumber', '$cyclic'),

  Date(Floor($1)) AS [Date] Tagged ('$axis', '$date', '$qualified'),

  Date(Floor($1), 'D') AS [_Date] Tagged ('$axis', '$date', '$hidden', '$simplified');

DERIVE FIELDS FROM FIELDS [ActualEnd], [Created_Date_Hour], [Resolved Date] USING [autoCalendarr] ;

I don't know how it can be modified to remove these days.

Thanks in advance.
