Pivot Table Row Lable Show Blank VBA

[Gregorys05]

Hi Guy's
I have a pivot table that i need one of the Row Lable Filters to only show blank values, i know in VBA i can go through and make all the other fields =
.visiable = False

But is there a way to say just show (Blank) without referencing every other value in the filter?

Any ideas guys as i dont really want to go through and make 50 odd values = false
