Top N & Bottom N at the same visual including hierarchies

[Ilias_pal]

Hello,

I have the below DAX Measure "FilterMeasure 3" added as filter in the visual which dynamically returns me the top 6 & bottom 2 "HRCHY_LVL_7" based on another measure "vs. Comparison Net Sales".

FilterMeasure 3 =

VAR CurrentBrand =

    SELECTEDVALUE ( 'Org Hierarchy Levels'[HRCHY_LVL_7] )

VAR T1 =

    ADDCOLUMNS (

        ALLSELECTED ( 'Org Hierarchy Levels'[HRCHY_LVL_7] ),

        "@PYSales", [vs. Comparison Net Sales]

    )

VAR Top6 =

    TOPN ( 6, T1, [@PYSales] )

VAR Bottom2 =

    TOPN ( 2, T1, [@PYSales], ASC )

VAR T2 =

    SELECTCOLUMNS ( UNION ( Top6, Bottom2 ), "@Brand", [HRCHY_LVL_7] )

RETURN

    IF ( CurrentBrand IN T2, 1 )

The measure works fine, however I would like to give the option to end users to  drill down more on hierarchy but I would like to always them to see the top 6 & bottom 2 based on the level they are. So my visual should be having the below on Y axis 

Unfortunately, the measure is not working with multiple data on Y Axis or it doesn`t give me for all levels the top 6 & bottom 2.

Can you please propose an idea how to resolve this?

Thank you very much in advance.
