Pop certain screens from stack

[dineshvg]

There is a popUnitl which pops everything till the desired screen.
If there was a method like popOnly(screen) that can iterate through the stack and remove a particular screen if it exists, that would be handy in some conditions.

Is there a way to do this already?

I would suggest creating an issue with this request
