Donut Drill down change colour

[Keitaru]

Hi,

I'm trying to achieve dimension drill down to change color upon selection but I notice that QlikSense doesn't have a getselectedfield().

How do I go about doing this?

First level before selectionAfter Selection

color for after selection:

pick(match([Process Status],'Not Started','Pending PR','Pending PO','Pending GR','Completed'),rgb(213,0,4),rgb(206,119,0),rgb(202,177,0),rgb(162,198,0),rgb(42,191,0))

I've attached the sample data
