Disconnected Table Slicer

Hi all,

I have 2 disconnected tables. I am taking data from one of the tables and a slicer (Patient Copay) from another. Now I need to filter grids based on the slicer. To do that Ia m creating a measure and putting it as a visual level filter on the grids. I have crated the measure but the issue that I am facing is that I have to make the slicer multiselect and combination of SWITCH and SELECTEDVALUE is not functioning properly. Below is my measure:

IF(ISFILTERED('Patient Copay Amount'[Patient Copay]),
SWITCH(
    TRUE(),
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "$0-$3000" && MAX(Copay Table[Total Copay])<=3000, 1,
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "$3000-$5000" && MAX(Copay Table[Total Copay])>3000 && MAX(Copay Table[Total Copay])<=5000, 1,
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "$5000-$7500" && MAX(Copay Table[Total Copay])>5000 && MAX(Copay Table[Total Copay])<=7500, 1,
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "$7500-$10000" && MAX(Copay Table[Total Copay])>7500 && MAX(Copay Table[Total Copay])<=10000, 1,
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "$10000-$12500" && MAX(Copay Table[Total Copay])>10000 && MAX(Copay Table[Total Copay])<=12500, 1,
    SELECTEDVALUE('Patient Copay Amount'[Patient Copay]) = "Above $12500" && MAX(Copay Table[Total Copay])>12500, 1,
    0
  ),1 
)

What I am doing now is putting the measure as visual level filter and putting it a 1. But this only works for single select

Thanks,

K
