Ignore Filter from Generated Table

So I used Greg_Deckler 's quartile function from here:

https://community.powerbi.com/t5/Quick-Measures-Gallery/QUARTILE/m-p/1064307

to create this measure in my report:

QUARTILE Orig = 
    VAR __Values = SELECTCOLUMNS('Quartile Table',"Values",[Revenue])
    VAR __Quart = MAX('Quartiles'[Quart])
    VAR __Median = MEDIANX(__Values,[Values])
    VAR __Count = COUNTROWS(__Values)
    VAR __Quartile =
        SWITCH(__Quart,
            0,MINX(__Values,[Values]),
            2,__Median,
            4,MAXX(__Values,[Values]),
            1,
                VAR __Median = IF(
                                    ISEVEN(__Count),
                                    MEDIANX(FILTER(__Values,[Values] < __Median),[Values]),
                                    MEDIANX(FILTER(__Values,[Values] <= __Median),[Values])
                                )
                RETURN __Median,
            3,
                VAR __Median = IF(
                                    ISEVEN(__Count),
                                    MEDIANX(FILTER(__Values,[Values] > __Median),[Values]),
                                    MEDIANX(FILTER(__Values,[Values] >= __Median),[Values])
                                )
                RETURN __Median
        )
RETURN
    __Quartile

I have a filter on the current page for another column in the Quartile Table called Supplier. When I filter for a particular supplier, the amounts for the above measure all simply return the same amount related to the supplier I selected which makes sense. I want to alter this measure so that when I filter for a supplier, it igornes the filter and returns the result for all suppliers instead. 

I tried putting ALL('Quartile Table'[Supplier]) pretty much everywhere possible, but that didn't really give me the right result either.
