double default in filter

[ary3170]

I need a double default in filter:

The first filter can assume two values ​​(A, B) and the second filter, 
connected to the first, has the values ​​1, 2, 3, 4, 5. 
If I open the report I want flag A and 1, 2, 3 as default, 
but if I move to B I want 4, 5 preselected. 
It is important to be able to select the remaining values ​​regardless of the default, 
so I must continue to display them all regardless of A or B.
