Concatenex con Rango

Lo resolví editando las medidas anteriores.

Primero creé una columna Ordenación en Power query desde fecha, columna y etapa

Date.Year([Fecha])*100000000
+Date.Month([Fecha])*1000000
+Date.Day([Fecha])*10000
+Texto.Fin([Etapa],1)

y editar la medida:

Stage Measure = 
VAR CurrentYear = SELECTEDVALUE('DateTable'[Year]) -- Gets the selected year from the DateTable
VAR Projects = DISTINCT('Stage table'[Project]) -- Get distinct projects for iteration
RETURN
CONCATENATEX(
    ADDCOLUMNS(
        FILTER(
            'Stage table',
            YEAR('Stage table'[Date]) = CurrentYear
        ),
        "Rank_Stage", 
        FORMAT(
            RANKX(
                FILTER(
                    'Stage table',
                    'Stage table'[Project] = EARLIER('Stage table'[Project]) &&
                    YEAR('Stage table'[Date]) = CurrentYear
                ),
                'Stage table'[Sorting],
                ,
                ASC
            ), "0"
        ) & " " & 'Stage table'[Stage]
    ),
    [Rank_Stage],
    ", ",
    'Stage table'[Date],
    ASC
)
