Two thoughts:
1. Custom member lists are defined in Finance Rule types, try putting your logic there. If you need a sample starter check our the List Ranked snippet.
2. This should be possible with regular member expansions and clever conditional formatting. It requires the use of indentation, the setup:
On your row pov:
U1#Total_Customers.ChildrenInclusive,
U6#Total_Employees.ChildrenInclusive
Header Formatting:
If ((RowE1IndentLevel = 0) AND (RowE2IndentLevel > 0)) Then
TextColor = Red
End If
That should highlight the rows you want to hide in Red. In theory, you should be able to replace the TextColor=Red with IsRowsVisible=False; but that doesn't seem to work. Feels like a bug to me.
