Extending Date List Values

I have a master calendar table in a Power BI report that is based on a Power BI-created list of dates. 

The problem is the dates do not extend far enough - only until June 30th 2022. I want to add dates into the future. 

Any suggestions on how to do this? 

This is the Advanced Editor code:

let
Source = List.Dates(StartDate, Length, #duration(1, 0, 0, 0)),
#"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "Date"}}),
#"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"Date", type date}}),
StartDate = #date(2017, 7, 1),
Today = DateTime.Date(DateTime.LocalNow()),
Length = Duration.Days(Today-StartDate)+31,
#"Calendar View" = #"Changed Type",
#"Inserted Year" = Table.AddColumn(#"Calendar View", "Year", each Date.Year([Date]), Int64.Type),
#"Inserted Month Name" = Table.AddColumn(#"Inserted Year", "Month Name", each Date.MonthName([Date]), type text),
#"Inserted Month" = Table.AddColumn(#"Inserted Month Name", "Month", each Date.Month([Date]), Int64.Type),
#"Inserted Week of Year" = Table.AddColumn(#"Inserted Month", "Week of Year", each Date.WeekOfYear([Date]), Int64.Type),
YearMonth = Table.AddColumn(#"Inserted Week of Year", "YYMM", each ([Year]-2000)*100 + [Month]),
#"Changed Type1" = Table.TransformColumnTypes(#"YearMonth",{{"YYMM", Int64.Type}}),
#"Added MonthID" = Table.AddColumn(#"Changed Type1", "MonthID", each (Date.Year([Date]) - Date.Year(StartDate))*12 + Date.Month([Date])),
#"Changed Type2" = Table.TransformColumnTypes(#"Added MonthID",{{"MonthID", Int64.Type}}),
// =IF(MONTH(date)>6,YEAR(date)&"-"&YEAR(date)+1,YEAR(date)-1&"-"&YEAR(date))
FY = #"Changed Type2",
#"Added Custom" = Table.AddColumn(FY, "Custom", each if [Year]=2017 and [Month]<=6 then "FY1617"
else if [Year]=2017 and [Month]>=6 then "FY1718"
else if [Year]=2018 and [Month]<=6 then "FY1718"
else if [Year]=2018 and [Month]>=6 then "FY1819"
else if [Year]=2019 and [Month]<=6 then "FY1819"
else if [Year]=2019 and [Month]>=6 then "FY1920"
else if [Year]=2020 and [Month]<=6 then "FY1920"
else if [Year]=2020 and [Month]>=6 then "FY2021"
else if [Year]=2021 and [Month]<=6 then "FY2021"
else if [Year]=2021 and [Month]>=6 then "FY2122"
else if [Year]=2022 and [Month]<=6 then "FY2122"
else "FY2223"),
#"Renamed Columns1" = Table.RenameColumns(#"Added Custom",{{"Custom", "FY"}})
in
#"Renamed Columns1"

let
    Startdate = #date(2020,1,1),
    Span = 5,
    Dates = Table.FromList(List.Dates(Startdate, Duration.TotalDays(Date.EndOfYear(Date.AddYears(Startdate,Span))-Startdate)+1,#duration(1,0,0,0)), Splitter.SplitByNothing(), {"Date"}),
    FY = Table.AddColumn(Dates, "FY",
        each let
            yr = Number.Mod(Date.Year([Date]),100)
            in if Date.Month([Date])>=6 then "FY" & Text.From(yr) & "-" & Text.From(yr+1) else "FY" & Text.From(yr-1) & "-" & Text.From(yr)
    )
in
    FY

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

@Barrettone 

here a solution I found helpful. It is verly likely there will be solution more efficient than mine.

In any case  you can set date by Manage Parameters.

/* StartingYear come from a parameter with data input = "mm/dd/yyyy*/
/* StartingYear should always start from January 1t */
StartDate = Date.From(StartingYear),
/* EndingYear come from a parameter with data input = "mm/dd/yyyy */
/* EndigYear should always ending at December, 31st */
EndDate = Date.From(EndingYear),
/*----------------------------------------------------------------------------------------------------------------------------*/

If I can...
