Get particular screen from Ui application stack

Hello..I want to know is there any way so that we can get particular screen instance from UI backstack of app.

For example :

We have 4 screens in the stack Screen1-Screen2-Screen3-Screen4


Now what if after reaching Screen4 we want to get Screen2 instance (to remove only Screen2  from backstack)


As per documentation UiApplication has getScreenBelow() method..But it only returns one screen below of active screen (In this case Screen3)


So is there any way to set some tag at push time and at any instance in any screen after detecting that tag we can get instance of decided screen ?

Re: Get particular screen from Ui application stack

you can call getScreenBelow multiple times.
to identify a certain screen you could use setCookie/getCookie.
As an alternative you could store a reference to your screen in a variable.
