I don’t really understand what you mean with “selection”.
But I think: Doing multi view along multi or single scene rendering is only a question of passes.
Make 4 viewports that you enable then render, and finally go to the next.
I think, 4 viewports means 4 passes.
Enable viewport #1 Place camera (or view) for the first viewport, then render.
Enable viewport #2 for second viewport, place camera and render…etc…

May be I’m Wrong…

if i am not wrong, let say you have create 4 view

createView() // view 1
createView() // view 2
createView() // view 3
createView() // view 4

then the current view or active view will always at the last view(in this case view 4 is the active view).
if you would like to active view 1. You should do it like this

createView() // view 2
createView() // view 3
createView() // view 4
createView() // view 1
