Default Drilldown on Column Header

[newpbiuser01]

Hello,

I have a matrix visual that has multiple level column headers. I know its possible to drilldown the row headers by going to Format Visual ->Row Header and then clicking on +/- icons. Would anyone know if that's possible with the column header? I know its possible to click on the arrow on top of the visual to keep drilling to the lowest value, but I'd like to default to drilldown to the lowest leve. Thank you so much for your help!

@newpbiuser01 , I doubt you can have +/- button for column headers
