Windows groups with window splits

[David Chanters]

Hi -

i don't know if this has been asked before, but i am using the GIT
version of screen and am wondering if i can do the following:

Assume i have two windows under screen, window1 and window2.  In
window1 i issue the :split command and quite rightly then get a split
window.  However, if i then switch to window2, whichever split region
i was in switches to window2.  what i would rather is the split
windows are contained just to window1 - window2 should have no split
windows at all when i switch to it.

i've read that one can have window groups but theres very little
documentation - is this something which would allow me to achieve
this?

Thanks!

David
